| titleOfInvention | Catalytic membrane reaction preparation technology for diphenyl carbonate |
| abstract | The invention provides a catalytic membrane reaction preparation technology for diphenyl carbonate. The catalytic membrane reaction preparation technology is characterized in that a porous mass serves as a carrier, a microporous molecular sieve membrane-Y-type molecular sieve membrane is grown at first, and a microporous structural unit TS-1 is led into an HMS mesoporous molecular sieve to construct a microporous-mesoporous composite molecular sieve Ti-HMS-1/Y membrane. The molecular sieve membrane is used for dimethyl carbonate and phenolic ester exchange reaction to prepare diphenyl carbonate, the Ti-HMS-1 molecular sieve membrane layer plays a catalytic role, and the Y-type molecular sieve membrane layer plays a separating role, so that catalytic reaction and product separation are simultaneously carried out in the reaction process. Owing to the separation function of the catalytic membrane, products are unceasingly moved out of a reaction system, thermodynamic equilibrium limitation is broken, and the conversion rate of dimethyl carbonate and the yield of targeted products are increased. |
