MoO3 Catalyst for Transesterification of Dimethyl Carbonate and Phenvl Acetate to Diphenvl Carbonate
摘要
Abstract
Catalytic activities of some metal oxides in transesterification of dimethyl carbonate ( DMC) and phenyl acetate(PA) to diphenyl carbonate(DPC) were investigated. It was found that the selfmade MoO3 showed the highest activity and the appropriate calcination temperature for MoO3 was 400 ℃ and 500 ℃. Under the conditions of MoO3 calcination temperature 400℃, transesterification reaction temperature 180 ℃, mole ratio of DMC to PA 1 : 2, reaction time 6 h and mole ratio of catalyst to PA 0. 05, the conversion of DMC, the selectivity to DPC and the selectivity to methyl phenyl carbonate were 74. 0% , 39. 5% and 56. 7% , respectively. And the MoO3 catalysts could be regenerated and reused many times.关键词
