摘　　要：以非质子酸为催化剂，以乙酸和异戊醇为原料，对合成乙酸异戊酯的反应进行了研究，探讨了几种不同非质子酸催化剂的影响并分析了醇酸摩尔比、催化剂用量、反应时间、回流温度诸因素对收率的影响．实验结果表明，四氯化锡是合成乙酸异戊酯的良好催化剂；最佳反应条件为：乙酸、异戊醇和四氯化锡的摩尔比为1：1．20：0．02，反应时间为45min，回流温度为130～140℃。满足上述条件酯收率可达93．61％。This paper introduced a process of preparing isoamyl acetate from acetic acid and isoamyl alcohol with non - acid catalyst. And investigated the influences of different kinds of catalysts, molar ratio of isoamyl alcohol to acetic acid, the amount of catalysts, time and temperature on the reaction. The optimizedconditions are as follows ： molar ratio of acetic acid to isoamyl alcoholand SnCl4 · 5H20 are 1：1.20：0.02; the reaction time is 45min; the reaction temperature is 118 - 138℃. The results showed that the esterification rate is over 93.61%.
