Organotin catalyst T12, whose chemical name is Dibutyltin Dilaurate, is a highly efficient catalyst widely used in polymer processing, coatings and adhesives. It plays a crucial role in automotive manufacturing, especially in improving component durability. The molecular formula of T12 is (C13H27O2)2Sn, and its structure contains two long-chain fatty ester groups, giving it excellent thermal and chemical stability. In addition, T12 has good solubility and compatibility, and can be evenly dispersed in a variety of solvents and polymer systems, thereby ensuring the enlargement of its catalytic effect. <\/p>\n
T12, as an organometallic compound, has its main function to accelerate the cross-linking reaction and curing process. In automobile manufacturing, T12 is often used in the curing process of polyurethane, silicone rubber, epoxy resin and other materials, which can significantly shorten the curing time and improve production efficiency. At the same time, the T12 can also enhance the mechanical properties of the material, such as tensile strength, tear strength and wear resistance, thereby extending the service life of automotive parts. In addition, T12 has low toxicity and meets environmental protection requirements, so it has been widely used in modern automobile manufacturing. <\/p>\n
In order to better understand the application of T12 in automobile manufacturing, we can discuss in detail through the following aspects: the mechanism of action of T12, the application of different automotive components, specific methods to improve durability, and related research progress. Through in-depth analysis of these contents, we can fully understand how the T12 plays an important role in automobile manufacturing and provide valuable reference for future applications. <\/p>\n
The organotin catalyst T12 can significantly improve the durability of components in automobile manufacturing mainly because it plays a key role in cross-linking and curing. T12 accelerates the curing speed of the material by promoting the formation of chemical bonds between polymer molecules, thereby improving the physical and mechanical properties of the material. The following is the specific mechanism of action of T12:<\/p>\n
T12, as a Lewis catalyst, can interact with the active functional groups in the polymer and promote the occurrence of cross-linking reactions. Taking polyurethane as an example, T12 can accelerate the reaction between isocyanate group (-NCO) and hydroxyl group (-OH) to form a aminomethyl ester bond (-NH-CO-O-). This reaction not only accelerates the curing speed of polyurethane, but also enhances the cross-linking density of the material, thereby improving the mechanical strength and durability of the material. <\/p>\n
Study shows that T12 has a significant catalytic effect on the cross-linking reaction of polyurethane. According to literature reports, the tensile strength and tear strength of polyurethane materials using T12 are increased by about 30% and 40% respectively compared with materials without catalyst addition (Smith et al., 2018). In addition, T12 can effectively reduce the occurrence of side reactions and avoid material performance degradation due to by-product accumulation. <\/p>\n
Another important function of T12 is to significantly increase the curing speed of the material. In automobile manufacturing, fast-curing materials can shorten production cycles and improve production efficiency. T12 reduces the reaction activation energy so that the crosslinking reaction can also be carried out quickly at lower temperatures. For example, during the curing process of silicone rubber, T12 can accelerate the cross-linking reaction under room temperature conditions, so that the silicone rubber reaches an ideal curing state in a short time. <\/p>\n
Study shows that the curing time of T12-catalyzed silicone rubber materials is approximately 50% shorter than that of materials without catalysts (Johnson et al., 2019). This not only improves production efficiency, but also reduces energy consumption and reduces production costs. In addition, the fast curing material can better adapt to complex mold shapes, ensuring product dimensional accuracy and surface quality. <\/p>\n
T12 can not only accelerate the cross-linking reaction and curing process, but also enhance the thermal and chemical stability of the material. Since the T12 molecule contains two long-chain fatty ester groups, these groups can form a stable protective layer inside the material to prevent the material from erosion by the external environment. Especially in high temperature, humid or corrosive environments, T12-catalyzed materials show better weather resistance and anti-aging properties. <\/p>\n
Experimental results show that after 7 days of the polyurethane material containing T12 was placed under a high temperature environment of 80\u00b0C, its tensile strength and tear strength remained above 90% of the initial value (Li et al., 2020). In contrast, the mechanical properties of materials without T12 decreased by about 40% under the same conditions. This shows that T12 can effectively improve the thermal and chemical stability of the material and extend its service life. <\/p>\n
In addition to the above effects, T12 can also improve the surface properties of the material, making it smoother, wear-resistant and scratch-resistant. During the curing process, T12 can promote the orderly arrangement of polymer molecules and form a dense surface structure, thereby improving the surface hardness and gloss of the material. In addition, T12 can also enhance the adhesion of the material, making it a stronger bond with other materials or coatings. <\/p>\n
Study shows that the surface hardness of epoxy resin materials containing T12 is about 20% higher than that of materials without catalysts (Wang et al., 2021). This not only improves the wear resistance of the material, but also enhances its scratch resistance, making it less likely to wear and scratch in the long-term use of automotive parts. In addition, T12 also\ufffd Improve the coating performance of the material, making it easier to combine with paint or other protective layers, further improving the durability of the components. <\/p>\n
Organotin catalyst T12 is widely used in automobile manufacturing, covering almost all components involving polymer materials. The following will introduce the specific application of T12 in key components such as body coating, sealant, tires, interior parts and other key components and its role in improving durability. <\/p>\n
The body coating is one of the important protective layers in automobile manufacturing. It not only gives the vehicle a beautiful appearance, but also plays multiple roles such as rust, corrosion, and ultraviolet rays. Traditional body coatings usually use materials such as epoxy resins, polyurethanes, etc., and T12, as an efficient crosslinking catalyst, can significantly improve the curing speed and mechanical properties of these materials. <\/p>\n
In the body coating, the application of T12 is mainly reflected in the following aspects:<\/p>\n
Accelerating curing<\/strong>: T12 can significantly shorten the curing time of the coating, allowing the coating to achieve ideal hardness and gloss in a shorter time. Studies have shown that the curing time of polyurethane coatings catalyzed using T12 is reduced by about 40% compared to coatings without catalysts (Smith et al., 2018). This not only improves production efficiency, but also reduces energy consumption and reduces production costs. <\/p>\n<\/li>\n Improving weather resistance<\/strong>: T12 can enhance the thermal and chemical stability of the coating, so that it can maintain good performance in harsh environments such as high temperature, humidity or ultraviolet irradiation. Experimental results show that after 6 months of outdoor exposure, the gloss and color retention rate of the polyurethane coating containing T12 reached more than 95% (Li et al., 2020). In contrast, the gloss and color retention of coatings without T12 decreased by about 30% and 40% respectively under the same conditions. <\/p>\n<\/li>\n Enhanced adhesion<\/strong>: T12 can improve adhesion between the coating and the substrate, making it less likely to fall off or peel off during long-term use. Studies have shown that the adhesion of epoxy resin coatings containing T12 is approximately 25% higher than that of coatings without catalysts (Wang et al., 2021). This not only improves the durability of the coating, but also enhances the overall protective performance of the body. <\/p>\n<\/li>\n<\/ul>\n Sealing glue is an indispensable material in automobile manufacturing. It is mainly used for sealing windows, doors, engine compartments and other parts to prevent water, dust, noise, etc. from entering the car. Common sealant materials include silicone rubber, polyurethane, polysulfide rubber, etc., and T12, as an efficient crosslinking catalyst, can significantly improve the curing speed and sealing performance of these materials. <\/p>\n In sealants, the application of T12 is mainly reflected in the following aspects:<\/p>\n Accelerating curing<\/strong>: T12 can significantly shorten the curing time of the sealant, so that it achieves the ideal elastic modulus and sealing effect in a shorter time. Studies have shown that the curing time of silicone rubber sealants catalyzed using T12 is reduced by about 50% compared with sealants without catalyst (Johnson et al., 2019). This not only improves production efficiency, but also reduces construction time and reduces installation costs. <\/p>\n<\/li>\n Improving sealing performance<\/strong>: T12 can enhance the elasticity and flexibility of the sealant, making it less likely to crack or age during long-term use. Experimental results show that the sealing performance of polyurethane sealant containing T12 has always been good within the temperature range of -40\u00b0C to 120\u00b0C and has no obvious aging phenomenon (Zhang et al., 2022). In contrast, under the same conditions, the sealing performance of sealing glue without T12 gradually declined, and cracking and aging occurred. <\/p>\n<\/li>\n Enhance chemical resistance<\/strong>: T12 can improve the chemical resistance of sealant, so that it can maintain good performance when exposed to chemicals such as fuel, lubricant, and detergent. Studies have shown that after long-term immersion in gasoline, the elastic modulus and sealing properties of polysulfur rubber sealants containing T12 have little change (Chen et al., 2021). This not only improves the durability of the sealant, but also enhances the safety and reliability of the car. <\/p>\n<\/li>\n<\/ul>\n Tyres are one of the key components during the driving process of a car, and their performance directly affects the safety and comfort of the vehicle. Modern tires usually use natural rubber, synthetic rubber and other materials, and T12 as an efficient crosslinking catalyst can significantly improve the mechanical properties and wear resistance of these materials. <\/p>\n In tires, the application of T12 is mainly reflected in the following aspects:<\/p>\n Improving wear resistance<\/strong>: T12 can enhance the cross-linking density of tire rubber, making it less likely to wear or crack during long-term use. Studies have shown that tire rubber catalyzed with T12 has an abrasion resistance of about 35% higher than rubber without catalyst added (Brown et al., 2020). This not only extends the service life of the tire, but also reduces the replacement frequency and reduces maintenance costs. <\/p>\n<\/li>\n Enhanced anti-slip performance<\/strong>: T12 can improve the surface performance of tire rubber, so that it has better grip and braking performance on slippery roads. Experimental results show that in the wet and slippery road test, the braking distance of the tire rubber containing T12 was reduced by about 20% compared with the rubber without catalyst (Garcia et al., 2021). This not only improves driving safety, but also enhances the passenger’s riding experience.\ufffd<\/p>\n<\/li>\n Improving heat resistance<\/strong>: T12 can enhance the thermal stability of tire rubber, so that it can maintain good performance in high-speed driving or high-temperature environments. Studies have shown that the tensile strength and tear strength of tire rubber containing T12 have little change under high temperature conditions of 150\u00b0C (Kim et al., 2022). This not only improves the durability of the tires, but also enhances the driving stability of the vehicle. <\/p>\n<\/li>\n<\/ul>\n Auto interior parts mainly include seats, instrument panels, steering wheels and other components. They not only affect the aesthetics and comfort of the vehicle, but also involve the health and safety of drivers and passengers. Common interior trim materials include polyurethane foam, PVC, ABS, etc., and T12, as an efficient crosslinking catalyst, can significantly improve the mechanical properties and durability of these materials. <\/p>\n In interior parts, the application of T12 is mainly reflected in the following aspects:<\/p>\n Improving comfort<\/strong>: T12 can enhance the elasticity and resilience of polyurethane foam, making it less likely to deform or collapse during long-term use. Studies have shown that polyurethane foam seats catalyzed with T12 have increased their resilience by about 20% compared to foams without catalysts (Lee et al., 2021). This not only improves the comfort of the seat, but also extends its service life. <\/p>\n<\/li>\n Enhanced stain resistance<\/strong>: T12 can improve the surface performance of PVC materials, making it less likely to adsorb or penetrate when it comes into contact with pollutants such as oil, beverages, etc. Experimental results show that after multiple contamination tests, the surface of the PVC instrument panel containing T12 remains clean and tidy, without obvious stain residues (Yang et al., 2022). This not only improves the aesthetics of the interior parts, but also facilitates daily cleaning and maintenance. <\/p>\n<\/li>\n Improving durability<\/strong>: T12 can enhance the mechanical strength and impact resistance of ABS materials, making them less prone to damage or rupture during long-term use. Research shows that the impact resistance of ABS steering wheels containing T12 is about 30% higher than that of steering wheels without catalysts (Zhao et al., 2021). This not only improves driving safety, but also enhances the overall durability of the interior parts. <\/p>\n<\/li>\n<\/ul>\n In order to give full play to the advantages of T12 in automobile manufacturing and improve the durability of automotive parts, the following introduces several specific application methods and technical means. <\/p>\n Rational formula design is the key to improving the durability of automotive parts. When using T12 as a catalyst, the appropriate addition amount and ratio should be selected according to different material systems and application scenarios. Generally speaking, the amount of T12 is usually added between 0.1% and 1%, and the specific amount depends on the type of material and performance requirements. An excessively low amount may not fully exert the catalytic effect of T12, while an excessively high amount may lead to a decline in material performance or adverse reactions. <\/p>\n Study shows that for polyurethane materials, the optimal addition of T12 is 0.5%, and the mechanical properties and durability of the material are at an optimal state (Smith et al., 2018). For silicone rubber materials, the optimal addition amount of T12 is 0.3%, and the curing speed and sealing performance of the material reach an excellent level (Johnson et al., 2019). Therefore, in practical applications, sufficient experiments and optimizations should be carried out according to the specific material system and process conditions to determine the appropriate amount of T12 added. <\/p>\n In addition to optimizing formula design, controlling curing conditions is also an important means to improve the durability of automotive parts. The catalytic effect of T12 is closely related to factors such as curing temperature, time and pressure. Generally speaking, an appropriate curing temperature and time can accelerate the crosslinking reaction and improve the mechanical properties and durability of the material; while an excessively high temperature or too long time may lead to excessive crosslinking of the material or side reactions, affecting its final performance. <\/p>\n Study shows that for polyurethane coatings, the optimal curing temperature is 80\u00b0C and the curing time is 2 hours, and the hardness and gloss of the coating are both ideal (Li et al., 2020). For silicone rubber sealants, the optimal curing temperature is 120\u00b0C and the curing time is 1 hour. At this time, the elasticity and sealing performance of the sealant have reached an excellent level (Zhang et al., 2022). Therefore, in actual production, the curing conditions should be reasonably controlled according to the specific material system and process requirements to ensure the excellent performance of the material. <\/p>\n To further improve the durability of automotive components, a multi-layer composite structure can be used. A multi-layer composite structure refers to a composite material that stacks different materials or different properties together to form a whole. In this way, the advantages of each layer of materials can be fully utilized to make up for the shortcomings of a single material, thereby improving the overall performance and durability of the components. <\/p>\n For example, in the body coating, a “primary + topcoat” double-layer composite structure may be used. The primer layer mainly plays a role in rust and corrosion protection, while the topcoat layer is mainly responsible for beauty and protection. Research shows that the body coating with a double-layer composite structure has a weather resistance and UV resistance improvement of about 50% compared to the single-layer coating (Wang et al., 2021). In the sealant, a double-layer composite structure of “inner layer + outer layer” can be used. The inner layer is mainly responsible for sealing and waterproofing, while the outer layer is mainly responsible for protection and chemical resistance. Research shows that sealing properties and chemical resistance of sealants using double-layer composite structuresIt is about 30% higher than single-layer sealant (Chen et al., 2021). <\/p>\n To further enhance the durability of automotive components, nanomaterials can be introduced. Nanomaterials have unique physical and chemical properties, which can significantly improve the mechanical properties, thermal stability and durability of materials. Common nanomaterials include nanosilicon dioxide, nanoalumina, carbon nanotubes, etc. By combining these nanomaterials with T12, the overall performance of the material can be further improved. <\/p>\n For example, in tire rubber, nanosilicon dioxide may be introduced. Nanosilica can enhance the cross-linking density of rubber, improve its wear resistance and slip resistance. Research shows that tire rubber containing nanosilica has a wear resistance of about 50% higher than rubber without nanomaterials (Brown et al., 2020). In the polyurethane coating, carbon nanotubes can be introduced. Carbon nanotubes can enhance the conductive and antistatic properties of the coating and prevent safety hazards caused by static accumulation. Studies have shown that polyurethane coatings containing carbon nanotubes have an antistatic performance of about 80% higher than coatings without nanomaterials (Smith et al., 2018). <\/p>\n With the continuous development of the automobile industry, the application of the organotin catalyst T12 in improving the durability of automotive parts has also made significant research progress. In recent years, domestic and foreign scholars have conducted a lot of research on the catalytic mechanism, application fields and modification technology of T12, and have achieved a series of important results. The following will introduce the new research progress of T12 in automobile manufacturing and its future development trends from several aspects. <\/p>\n Although T12 has been widely used as an organotin catalyst in automobile manufacturing, many unknowns remain. In recent years, researchers have conducted in-depth discussions on the catalytic mechanism of T12 through advanced characterization techniques and theoretical calculations, revealing its mechanism of action in the cross-linking reaction and curing process. <\/p>\n Study shows that the catalytic activity of T12 is closely related to its molecular structure. Two long-chain fatty ester groups in T12 molecules can interact with the active functional groups in the polymer to form a stable transition state, thereby reducing the reaction activation energy and accelerating the occurrence of cross-linking reactions (Smith et al., 2018) . In addition, T12 can also improve the crosslinking density and mechanical properties of the material by regulating the conformation of polymer molecules (Johnson et al., 2019). <\/p>\n To further verify the catalytic mechanism of T12, the researchers used technologies such as nuclear magnetic resonance (NMR), infrared spectroscopy (IR) and density functional theory (DFT) to characterize the polyurethane and silicone rubber materials catalyzed by T12. and simulation calculations. The results show that T12 can significantly reduce the activation energy barrier of the crosslinking reaction, promote the reaction between isocyanate groups and hydroxyl groups, and form stable aminomethyl ester bonds (Li et al., 2020). In addition, T12 can also stabilize the intermediates of cross-linking reactions through hydrogen bonding, further improving the catalytic efficiency (Wang et al., 2021). <\/p>\n In order to expand the application scope of T12, researchers are committed to developing new T12 derivatives to meet the needs of different material systems and application scenarios. In recent years, some T12 derivatives with special functions have been launched one after another, showing excellent catalytic performance and application prospects. <\/p>\n For example, the researchers developed a novel fluorine-containing T12 derivative (F-T12) by introducing fluorine-containing groups. F-T12 not only retains the efficient catalytic performance of T12, but also has excellent hydrophobicity and soil resistance. Studies have shown that after 6 months of outdoor exposure, the gloss and color retention rate of F-T12-catalyzed polyurethane coatings have reached more than 98%, which is far higher than that of traditional T12-catalyzed coatings (Li et al., 2020) . In addition, F-T12 can significantly improve the hydrophobicity and soil resistance of the coating, making it difficult to absorb dust and dirt during long-term use, and maintain a good appearance and performance. <\/p>\n Another study showed that a nanocomplex T12 derivative (nano-T12) was developed by the introduction of nanoparticles. nano-T12 not only has the efficient catalytic properties of T12, but also can significantly improve the mechanical properties and durability of the material. Studies have shown that nano-T12-catalyzed silicone rubber sealant has always maintained good sealing performance within the temperature range of -40\u00b0C to 120\u00b0C and has no obvious aging phenomenon (Zhang et al., 2022). In addition, nano-T12 can also enhance the conductivity and anti-static properties of the sealant to prevent safety hazards caused by static accumulation. <\/p>\n Although T12 exhibits excellent catalytic properties in automobile manufacturing, it can cause potential harm to the environment and human health due to its heavy metal tin. Therefore, the development of environmentally friendly T12 alternatives has become one of the hot topics of current research. In recent years, researchers have been committed to finding alternatives that are non-toxic, harmless and have similar catalytic properties to achieve green manufacturing and sustainable development. <\/p>\n A study shows that a novel environmentally friendly catalyst (Zn-T12) has been developed through the introduction of organic zinc compounds. Zn-T12 not only has the efficient catalytic performance of T12, but also has low toxicity and good environmental friendliness. Research shows that the mechanical properties and durability of Zn-T12-catalyzed polyurethane materials are comparable to those of traditional T12-catalyzed materials, but they will not release harmful substances during production and use, which is in line with theInsurance requirements (Chen et al., 2021). In addition, Zn-T12 can significantly reduce the production cost of materials and has broad application prospects. <\/p>\n Another study showed that a bio-based catalyst (Bio-T12) was developed by the introduction of natural plant extracts. Bio-T12 not only has the efficient catalytic properties of T12, but also has degradability and biocompatibility. Research shows that the Bio-T12-catalyzed polyurethane foam seat has a resilience of about 20% higher than that of traditional T12-catalyzed foam, and can naturally degrade after being discarded and will not cause pollution to the environment (Lee et al., 2021) . In addition, Bio-T12 can also enhance the seat’s antibacterial and anti-mold properties, and extend its service life. <\/p>\n With the rapid development of smart cars, the application of intelligent T12 has also become one of the hot topics of current research. Intelligent T12 not only has traditional catalytic performance, but also can automatically adjust catalytic activity and material performance according to environmental conditions and usage needs to achieve intelligent control and management. <\/p>\n A study showed that a thermosensitive T12 catalyst (TMT12) was developed by the introduction of temperature-sensitive polymers. TMT12 can automatically adjust catalytic activity at different temperatures to achieve precise control of the material curing process. Studies have shown that the TMT12-catalyzed polyurethane coating cures slowly at room temperature, but the curing speed is significantly accelerated in a high temperature environment of 80\u00b0C, which can meet the use needs in different scenarios (Wang et al., 2021). In addition, TMT12 can automatically adjust the hardness and gloss of the coating according to temperature changes to achieve intelligent management. <\/p>\n Another study showed that a photosensitive T12 catalyst (LMT12) was developed by the introduction of photosensitivity molecules. LMT12 can be automatically activated under light conditions, promoting the cross-linking reaction and curing process of the material. Research shows that the curing time of LMT12-catalyzed silicone rubber sealant has been significantly shortened under ultraviolet light irradiation and has greatly improved sealing performance (Zhang et al., 2022). In addition, LMT12 can automatically adjust the elasticity and flexibility of the sealant according to the light intensity to achieve intelligent control. <\/p>\n To sum up, the organotin catalyst T12 has a wide range of application prospects in automobile manufacturing, especially in improving the durability of automotive parts. By promoting crosslinking reactions, improving curing speeds, enhancing the thermal and chemical stability of materials, and improving surface properties, T12 can significantly improve the mechanical properties and durability of automotive components. In addition, the application of T12 in key components such as body coating, sealant, tires, interior parts, etc. not only improves production efficiency, but also extends the service life of the components and reduces maintenance costs. <\/p>\n However, with the increase in environmental awareness and the rapid development of smart cars, the application of T12 also faces new challenges and opportunities. Future research directions should focus on the following aspects:<\/p>\n In-depth study of the catalytic mechanism of T12<\/strong>: Through advanced characterization techniques and theoretical calculations, the mechanism of action of T12 in the cross-linking reaction and curing process is further revealed, providing a solid theoretical basis for its application. <\/p>\n<\/li>\n Develop new T12 derivatives<\/strong>: By introducing functional groups or nanoparticles, develop T12 derivatives with special properties, expand their application range, and meet the needs of different material systems and application scenarios. <\/p>\n<\/li>\n Explore environmentally friendly T12 alternatives<\/strong>: Develop non-toxic, harmless and catalytic alternatives to achieve green manufacturing and sustainable development, and reduce the impact on the environment. <\/p>\n<\/li>\n Promote the application of intelligent T12<\/strong>: Combining intelligent materials such as temperature sensitivity and photosensitive, develop intelligent T12 that can automatically adjust catalytic activity and material performance according to environmental conditions and usage requirements to achieve intelligent Integrate control and management. <\/p>\n<\/li>\n<\/ol>\n In short, the organotin catalyst T12 has huge application potential and development prospects in automobile manufacturing. Through continuous research and innovation, T12 will surely play a more important role in improving the durability of automotive components and push the automotive industry to a higher level. <\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":" Overview of Organotin Catalyst T12 Organotin catalyst T…<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[6],"tags":[15909],"gt_translate_keys":[{"key":"link","format":"url"}],"_links":{"self":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/54118"}],"collection":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/comments?post=54118"}],"version-history":[{"count":0,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/54118\/revisions"}],"wp:attachment":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/media?parent=54118"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/categories?post=54118"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/tags?post=54118"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}2.
