Abstract Various kinds of catalysts,including Lewis acid,molecular sieve,organic Ti and Sn compounds, and supported metal oxide catalysts,were employed to catalyze the transesterification of dimethyl carbonate(DMC) with phenol to produce diphenyl carbonate(DPC). The results indicated that MoO_3/SiO_2,TiO_2/SiO_2 showed preferable activity and selectivity. The conversion of DMC and selectivity of products DPC were 24.3% and 37.6% respectively over MoO_3/SiO_2, while 13.7% and 20.0% over TiO_2/SiO_2. In this reaction, SiO_2, compared with Al_2O_3 and MgO, was an excellent carrier of catalyst.
