摘　　要：介绍了影响抗氧剂合成中酯交换反应的主要因素,包括催化剂种类、反应温度和时间、醇酯摩尔比以及体系水含量等。探讨了酯交换反应机理:酯交换反应的活性体是金属醇化物。The main factors effecting transesterification in synthesizing antioxidant, such as catalysts type, reaction temperature, reaction time, molar ratio of alcohol to ester, as well as the moisture content, were introduced. The mechanism of the transesterification was discussion. The results showed that the transesterification active - part should be the metal alcoholate.
