| 摘 要： | 选择Lewis酸催化剂、分子筛催化剂、有机钛和锡化合物催化剂和不同负载型金属氧化物催化剂用于碳酸二甲酯(DMC)与苯酚酯交换合成碳酸二苯酯(DPC)的过程。试验结果表明，：MoO3/SiO2和TiO2／SiO2催化剂对该反应具有相对较好的催化活性和选择性。以MoO3／SiO2为催化剂，DMC转化率和DPC选择性分别为24.3％和37.6％；以TiO2／SiO2，为催化剂，DMC转化率和DPC选择性分别为13.7％和20.0％。在该酯交换反应中，SiO2与Al2O3和MgO相比，是一种良好的催化剂载体。

| 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. |
