Research Progress of Catalysts for Oxidative Carbonylation of Methanol to Dimethyl Carbonate

Synthesis of dimethyl carbonate has been much discussed in chemical industry both at home and abroad.The method of oxidative carbonylation of methanol is one of the effective methods to produce dimethyl carbonate.The research and development status of catalysts for synthesis of dimethyl carbonate by oxidative carbonylation of methanol are reviewed.Copper-based catalysts and reaction mechanism for synthesis of dimethyl carbonate by oxidative carbonylation of methanol in liquid-phase were discussed in detail.The results of various copper catalyst are compared.In order to promote the catalytic performance and selectivity of the catalyst,extending longer service life of the catalysts and inhibiting the reaction system,the reaction mechanism should be further studied and effective catalyst promoters and catalyst carriers should be added.
