Abstract

Abstract: The compound metal oxide LaxPbyMnzO used as support was prepared by the sol-gel method, and
the catalyst in which Pd was used as active component and Snas co-active component for
direct synthesis of diphenyl carbonate (DPC) with heterogeneous catalytic reaction was
obtained by co-calcination and precipitation respectively.The catalyst was characterized by
XRD, SEM and TEM respectively. The specific surface area of catalysts was measured by
ChemBET3000 instrument, and the activity of the catalysts was tested by the synthesis of
DPC in a pressured reactor. The results showed that when the co-active component Sn was
added by co-calcination method A, its loading content was equal to 14.43% and active
component Pd was loaded by precipitation, the yield and selectivity of DPC could reach
26.78% and 99% respectively.
