摘　　要：利用相转移催化剂催化合成乙酸异戊酯,最佳反应条件:催化剂用量1g/0.1mol异戊醇,酸醇比2:1,反应时间100min,收率77.56%。实验证明,相转移催化合成对该酯化反应是高效,低成本和实用的方法。Use of CTMAB as phase transfer catalyst on the esterification of isopentyl acetate was studied. The optimized conditions are following： the weight of catalyst is 1g/mol iso- Amyl ＇alcohol, the mole ratio of acid to alcohol is 2：1 and the reaction time is 100min. The yield was 77.56 % . Experiment results showed that phase transfcr catalyst （CTMAB）is highly active catalyst for this reaction.It is an inexpensive and very practical method.
