【Abstract】 Use of CTMAB as phase transfer catalyst on the esterification of ethyl acetate was studied.The optimized donditions are as following:the weight of catalyst is 0.5g/0.1mol ethanol,the mole ratio of alchol to acid is 2∶1 and the reaction time is 0.6h.The chemical yield was 97.81b%.Experiment results showed that phase transfer catalyst(CTMAB) is a highly active catalyst for this reaction.It is an inexpensive very practical method.更多还原
