Research process of heterogeneous catalysts for synthesis of diphenyl carbonate

The processes of transesterification include the reaction of dimethyl carbonate with phenol and dimethyl oxalate with phenol to diphenyl carbonate.The advances in the development of heterogeneous catalysts including metal oxides,zeolites,and the catalysts supported on zeolites,SiO_2,active carbon or the composite of metal oxide used in the process of transesterification and oxidative carbonylation are described in detail.The advantages and shortcomings of the synthetic routes and the catalysts are also commented.It is suggested that the development of heterogeneous catalysts should be the focus in the process for production of diphenyl carbonate.
