Progress in Synthesis of Diphenyl Carbonate by Transesterification of Dimethyl Carbonate and Phenol

Mechanism and thermodynamic properties of transesterification between dimethyl carbonate and phenol to diphenyl carbonate(DPC)were reviewed.DPC was key material for preparation of polycarbonate by non-phosgene method.Various categories of catalysts developed recently were surveyed,including homogeneous catalysts(alkali or alkali metal compounds,Lewis acids,organo-tin compounds,organo-titanium compounds,samarium trifluoromethanesulfonate etc.)and heterogeneous catalysts(some metallic oxides,hydrotalcite catalysts etc.).Recent development concerning transesterification mechanism on organotin,titanate and oxide catalysts was also reviewed.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.
