摘要:以乙酸和正丁醇为原料,在硫酸氢钾催化下合成了乙酸正丁酯;考察了反应时间、醇酸比、催化剂用量、带水剂用量及催化剂的重复使用对酯化率的影响.结果表明:当正丁醇用量为0.1mol,乙酸用量为0.135mol,催化剂硫酸氢钾用量为0.8g,带水剂环己烷用量为8mL时,反应的酯化率达95.2%.
Butyl acetate was synthesized with acetic acid and butyl alcohol as the raw materials and potassium bisulfate as the catalyst. The effects of reaction time, the ratio of alcohol to acid, dosage of catalyst, dosage of water-carrying agent, and the reuse of the catalyst on the esterification rate were investigated. Results show that an esterification rate of 95.2% is ob- tained when the dosage of butyl alcohol, acetic acid, potassium bisulfate catalyst, and water- carrying agent cyclohexane is set as 0.1 mol, 0. 135 mol, 0.8 g, and 8 mL.
