【Abstract】 Use of TBAB as phase trasfer catalyst on the estcrification of isopropyl acetate was studied. The optimized conditions are as following: the weight of catalyst is 0. 38 g/0. 1 mol acetic acid, the mole ratio of alchol to acid is 1 : 2 and the reaction time is 1h. The chemical yield was87. 2%. Experiment results showed that phase transfer catalyst (TBAB) is a highly active catalyst for this reaction. It is an inexpensive and very practical method.更多还原
