碳酸二甲酯合成研究新进展

碳酸二甲酯的合成研究受到了国内外研究者的广泛关注，合成路线正朝着简单化、无毒化和无污染化的方向发展。综述了国内外CO2和甲醇直接合成法、酯交换法和尿素醇解法合成碳酸二甲酯的研究进展，在均相催化体系、非均相催化体系、离子液体催化体系、超临界反应体系以及光催化反应体系下概述了上述方法的研究概况。由于上述方法合成碳酸二甲酯存在催化剂活性或选择性不高，产率低等缺点，今后寻找更加合适的催化剂及载体、提高催化剂的活性和选择性将成为研究重点。

The latest progresses in the study on the synthesis of dimethyl carbonate

Study on synthesis of dimethyl carbonate was concerned extensively by researchers at home and abroad,the synthetic routes were developing toward the directions of simple,non-toxic and non-pollution.The latest progresses in studies on preparing dimethyl carbonate including direct synthesis from CO2 and methanol,ester interchange and direct alcoholysis of urea were reviewed,under homogeneous catalysis system,non-homogeneous catalysis system,ionic liquids catalysis system,supercritical reaction system and photocatalysis reaction system.Due to the shortcomings,such as low selectivity,catalytic activity and yield of the methods of synthesis of dimethyl carbonate,looking for more suitable catalysts and carriers to enhance the activity and selectivity of catalysts would become research priorities in the future.
