碳酸二苯酯的合成研究进展

Research Progress in Synthesis of Diphenyl Carbonate

主要介绍了碳酸二苯酯的三种合成方法,即光气法、酯交换法和氧化羰基化法,其中对酯交换法和氧化羰基化法进行了详细的阐述。讨论了酯交换法中采用的催化剂、反应过程及装置以及反应中产生的共沸物的分离方法。论述了氧化羰基化法采用的催化剂体系。

Three methods including phosgenation, transesterification and oxidative carbonylation for synthesizing DPC were introduced. The latter two methods were described in detail. The catalysts, reactor and separating meth-ods for the azeotropic mixture in transesterification were emphasized. The catalyst systems in oxidative carbonylation were fully discussed.
