| titleOfInvention | The method that ester exchange prepares diphenyl carbonate |
| abstract | The present invention relates to a kind of method that ester exchange prepares diphenyl carbonate, the problem of mainly solving prior art and have that heterogeneous catalysis is active, selectivity is low, and easily inactivate.The present invention is by using using dimethyl carbonate and phenylacetate as raw material, it it is 120~190 DEG C in reaction temperature, the mol ratio of dimethyl carbonate and phenylacetate is 0.1~5, under conditions of the weight of catalyst and phenylacetate ratio is 0.01~0.5, raw material contacts 1~20 hour with catalyst, reaction generation diphenyl carbonate；The catalyst is binary mixed metal oxides A a O b /B c O d ；Wherein, A Sn, Mn or Bi, B Al, Ga, Fe, In, Zr or Cr technical scheme preferably solve the problem, are prepared available for dimethyl carbonate and phenylacetate ester exchange reaction in the industrial production of diphenyl carbonate. |
