Preparation method: <\/p>\n <\/p>\nIn a reaction bottle equipped with a stirrer, thermometer, and dropping funnel, add 800g of 30% hydrogen peroxide, cool it in an ice bath, and add dropwise a dilute solution composed of 800g of concentrated sulfuric acid and 310g of crushed ice while stirring and cool it to below 10\u00b0C. For sulfuric acid, control it at 5-10\u00b0C and finish adding it in about 20 minutes. Then, 224.4g (2.0mol) of 2,4,4-trimethyl-1-pentene (2) was added dropwise, and the addition was completed in 5 to 10 seconds. Remove the ice bath and stir the reaction at 25\u00b0C for 24 hours. Separate the organic layer and cool it in an ice bath, add 500g of 70% sulfuric acid dropwise with vigorous stirring, and keep the internal temperature at 15 to 25\u00b0C, which will take about 67 to 75 minutes. After the addition is completed, stir at 5 to 10\u00b0C for 30 minutes. Leave to stand for 1 to 3 hours, separate the organic layer, pour into 1000 mL of water, and distill under normal pressure (foam may appear, and distillation can be stopped at this time). After cooling the distilled liquid, separate the organic layer, dry it over anhydrous sodium sulfate\u2460<\/sup>, fractionate, collect the fractions between 111 and 113\u00b0C to obtain 2,2-dimethyl-1-propanol \u2461<\/sup>(1) 60\uff5e70, yield 34%\uff5e40%. Note: \u2460 Dry thoroughly before distillation, otherwise the product will form an azeotrope (80~85\u2103) with water, which will affect the yield. \u2461 This reaction is similar to the hydrogen peroxide oxidation of ethyl-propyl benzene to produce phenol and acetone. Under acidic conditions, the peroxide is rearranged to produce alcohol and acetone.

For sulfuric acid, control it at 5-10\u00b0C and finish adding it in about 20 minutes.

Exist in smoke. <\/p>\n<\/p>\nStorage method<\/h2>\n This product should be sealed and stored in a cool place. <\/p>\n<\/p>\nSynthesis method<\/h2>\n1. Preparation method: <\/p>\n <\/p>\nIn a reaction bottle equipped with a stirrer, thermometer, and dropping funnel, add 800g of 30% hydrogen peroxide, cool it in an ice bath, and add dropwise a dilute solution composed of 800g of concentrated sulfuric acid and 310g of crushed ice while stirring and cool it to below 10\u00b0C. For sulfuric acid, control it at 5-10\u00b0C and finish adding it in about 20 minutes. Then, 224.4g (2.0mol) of 2,4,4-trimethyl-1-pentene (2) was added dropwise, and the addition was completed in 5 to 10 seconds. Remove the ice bath and stir the reaction at 25\u00b0C for 24 hours. Separate the organic layer and cool it in an ice bath, add 500g of 70% sulfuric acid dropwise with vigorous stirring, and keep the internal temperature at 15 to 25\u00b0C, which will take about 67 to 75 minutes. After the addition is completed, stir at 5 to 10\u00b0C for 30 minutes. Leave to stand for 1 to 3 hours, separate the organic layer, pour into 1000 mL of water, and distill under normal pressure (foam may appear, and distillation can be stopped at this time). After cooling the distilled liquid, separate the organic layer, dry it over anhydrous sodium sulfate\u2460<\/sup>, fractionate, collect the fractions between 111 and 113\u00b0C to obtain 2,2-dimethyl-1-propanol \u2461<\/sup>(1) 60\uff5e70, yield 34%\uff5e40%. Note: \u2460 Dry thoroughly before distillation, otherwise the product will form an azeotrope (80~85\u2103) with water, which will affect the yield. \u2461 This reaction is similar to the hydrogen peroxide oxidation of ethyl-propyl benzene to produce phenol and acetone. Under acidic conditions, the peroxide is rearranged to produce alcohol and acetone.
