摘要

Abstract

The support of catalyst for the direct synthesis of diphenyl carbonate(DPC)by heterogeneous catalytic reaction was prepared by the sol-gel method.Compared with activated charcoal

molecular sieve

porous ceramics

hopcalite

the support prepared by the sol-gel method has higher activity.The characterization of the support by X-ray diffraction(XRD)and transmission electron microscope(TEM)show that the main crystal phase is Co

MnO

and the average particle diameter is about 40 nm.The optimum conditions for synthesis of the support were determined by orthogonal experiments

which indicate that the proportion of Cu

and Co is the first important factor influencing the yield and selectivity of DPC.Temperature of calcination is the second one.The optimum conditions are:molar proportion of Cu

and Co being 1:1:1

temperature of calcination 700℃

drying at 100℃

temperature of water bath 85℃.The yield and selectivity of DPC in the process can reach 38% and 99% in the batch operation

respectively.The copper cobalt manganese mixed oxides chosen as the support contribute more to the high catalytic activity than the sol-gel method.
