酯交换法合成碳酸二苯酯

The Method of Transesterification to Synthesize DPC

碳酸二苯酯(DPC)是一种重要的精细化工中间体,主要用于合成许多有机化合物和高分子材料。目前,合成碳酸二苯酯方法有光气法、氧化羰基化法和酯交换法。酯交换法合成DPC主要是通过苯酚与碳酸二甲酯(DMC)反应合成,在100～200℃常压或加压的条件下进行,反应设备简单、毒性和腐蚀性小,产率较高,是一种绿色合成方法。

DPC is an important fine chemical intermediates, and it is mainly used for the synthesis of many organic compounds and macromolecule materials. At present, the methods of synthesizing DPC are mainly phosgene, oxidation carbonylation and transesterification. The method of transesterification to synthesize DPC is mainly synthesized by the chemical reaction between phenol and DMC, which processes under the situation of Atmospheric pressure or pressurization. Its reaction equipment is simple, the production rate is higher, the synthetic method is Non- pollution, and it is the current main method of research.
