【Abstract】 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.更多还原
