摘　　要：综述了碳酸二甲酯-甲醇二元共沸物汽液平衡和分离方法的最新研究进展。在各种分离方法中,膜分离和吸附分离能耗低、效率高,是一种新型的分离方法;萃取精馏和共沸精馏具有设备简单、操作安全等优势,是分离提纯DMC CH3OH共沸物的有效手段。Vapor-liquid equilibria and separation of methanol-dimethyl carbonate azeotrope are reviewed in this paper. Separation by membrane or adsorption, which has the characteristics of low energy consumption and high efficiency, is a new separation method. Extractive rectification and azeotropic distillation, which use simple equipment, have high efficiency and operate more safely, are effective methods for separating dimethyl carbonate from methanol-dimethyl carbonate azeotrope in industry.
