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0．1 mol ，乙酸用量为0．135 mol ，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％．
以乙痠和正丁醇為原料，在硫痠氫鉀催化下閤成瞭乙痠正丁酯；攷察瞭反應時間、醇痠比、催化劑用量、帶水劑用量及催化劑的重複使用對酯化率的影響．結果錶明：噹正丁醇用量為0．1 mol ，乙痠用量為0．135 mol ，催化劑硫痠氫鉀用量為0．8g，帶水劑環己烷用量為8mL時，反應的酯化率達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 .
