Tue, 12 Nov 2019 06:52:56 +0000http://www.gengheonline.cn/?p=878Hydroxyethyl Ethylenediamine Hydroxyethyl ethylenediamine is a kind of chemical substance with the molecular formula of c4h12n2o. Chinese Name: hydroxyethyl Ethylenediamine Foreign names: β – hydroxyylenediamine, AEEA Other name: hydroxyethyl Ethylenediamine Commonly known as 120 curing agent, 1 × 1 curing agent, hydroxyethyl ethylenediamine, 120 curing agent, curing agent 1, aminoethyl brief introduction Chinese Name: hydroxyethylenediamine [1] Chinese nickname: β – hydroxyethyl ethylenediamine; N – (2-aminoethyl) ethanolamine; N – (2-hydroxyethyl) ethylenediamine; β – hydroxyethylenediamine; aminoethyl; aminoethyl ethanolamine; curing agent 1; hydroxyethyl ethylenediamine; aminoethyl ethanolamine Common name: 120 curing agent, curing agent 1# English Name: β – hydroxyylenediamine English nickname: 2 – (2 aminethylamino) ethanol; aminethylethanolamin; n-hydroxyethyl-1,2-ethanediamine Structural formula: c4h12n2o Molecular weight: 104.15 CAS No.: 111-41-1 Appearance: colorless or light yellow transparent viscous liquid Odor: slightly ammonia Density: 1.03 g / ml at 25 ° C (lit.) Vapor density: 3.6 (vs air) Refractive index: N20 / D 1.485 (lit.) Melting point: – 28 ° C Boiling point: 238-240 ° c752 mm Hg (lit.) Flash point: > 230 ° f Viscosity (20 ℃): 141ma. S Solubility: miscible with water, ethanol and toluene, slightly soluble in ether Toxicity: low toxicity, LD50 3600 ~ 4450mg / kg Chemical property Colorless, light yellow transparent viscous liquid. It is hygroscopic, strongly alkaline and slightly ammonia It is miscible with water and alcohol, slightly soluble in ether. Production method It is obtained by the reaction of ethylenediamine with ethylene oxide. purpose It is used to produce dye, resin, rubber, flotation agent, insecticide and surfactant, and the prepared inhibitor 1017 is used in petrochemical production. The product is a good low toxicity room temperature curing agent for epoxy resin, which is obviously superior to ethylenediamine. It is widely used for bonding various metal and non-metal parts, preparing anticorrosive epoxy coating, casting cable joints and other mechanical and electrical parts. Used in shampoo, lubricant, oilfield buffer, resin synthesis, textile assistant, imidazoline amphoteric surfactant, etc Used as curing agent for plastics For organic synthesis Risk terminology R34 causes burns. R43 may be sensitized in contact with skin. R61 may cause harm to the fetus.
