Research progress of catalyst for direct synthesis of dimethyl carbonate from carbon dioxide
Dimethyl carbonate(DMC) is an important green chemical material,and it has been applied widely in industry,agriculture and pharmaceutical industry.DMC has a variety of synthetic methods,of which the phosgene methanol method,transesterification method and oxidation carbonylation have been industrialized,but their own shortcomings limit their scale.In recent years,the method of synthesizing DMC using carbon dioxide and methanol is researched and regarded as the greenest synthetic method.The application of catalysts for this method and the research progress of the catalytic mechanism are presented,and recommendations on the problems of catalysts are put forward.
