摘　　要：本文利用相转移催化剂TEBAC催化合成乙酸苄酯，最佳反应条件如下：氯化苄：乙酸钠：TEBAC=1：2：0．04．反应温度为110—115℃，反应时间为3h，酯收率达86．7％。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 TEBAC as phase transfer catalyst on the esterifieation of bonzyl acetate was studied. The optimized conditions are following：the mole ratio of benzyle chloride to sodium acetate to TEBAC is 1：2：0.04 and temperature 110 - 115 ℃, the reaction time is 3h, The chemical yield was 86.7%. Experiment results showed that phase transfer catalyt TEBAC is highly active catalyst for this reaction. It is an inexpensive and very practical method.
