Abstract

Abstract:

Ethyl methyl carbonate (EMC) is an eco-friend asymmetric carbonate, which has been widely used as solvent and/or organic synthetic intermediate. Its market demand has rapidly increased with the development of lithium-ion batteries. In this paper, the development of the synthesis methods of EMC was briefly introduced including the phosgene method, oxidative carbonylation and transesterification. The review focused on the research of the catalysts used in transesterification, which is the most promising method for green synthesis EMC due to the mild reaction conditions and easy control. The types, structures, properties and catalytic performances of the catalysts used in this route were discussed and analyzed in detail, and the problems in current researches were also summarized. Finally, the research direction and the development trend of the catalysts were analyzed and prospected for the synthesis EMC with transesterification method. The development of economic, efficient, stable and simple heterogeneous catalyst, and its coupling with reactive distillation technology is the main development trend in the future, which is expected to provide valuable reference for the efficient synthesis of EMC.

Key words: transesterification, ethyl methyl carbonate, catalyst, synthesis, reaction, reactivity
