| Abstract: | 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. |
