The progress of catalysts in synthesis of diphenyl carbonate by transesterification of dimethyl carbonate and phenol

The systems of catalysts developed recently of transesterification between dimethyl carbonate and phenol to diphenyl carbonate(DPC) were reviewed,including homogeneous catalysts(alkali or alkali metal compounds,Lewis acids,organo-tin compounds,organo-titanium compounds,etc.) and heterogeneous catalysts(the catalysts supported on zeolites,SiO2,active carbon or others,the composite of metal oxide,the organic anion-pillared hydrotalcites,etc.).The development and immobilization of tin and titanium compounds were thought as important research trends for transesterification of dimethyl carbonate and phenol to diphenyl carbonate.
