摘要
利用相转移催化剂催化合成乙酸异丙酯 ,最佳反应条件如下 :催化剂用量 0 38g/ 0 .1mol乙酸 ,醇酸比 1:2 ,反应时间 1h ,收率 94 16 %。实验证明 ,相转移催化对该酯化反应是高效 。
Use of CTMAB as phase trasfer catalyst on the esterification of isopropyl acetate was studied.The optimized donditions are as following:the weight of catalyst is 0.38g/0.1mol acetic acid,the mole ratio of alchol to acid is 1:2 and the reaction time is 1 h.The chemical yield was 94.2%.Experiment results showed that phase transfer catalyst(CTMAB) is a highly active catalyst for this reaction.It is an inexpensive and very practical methed.
