| titleOfInvention | Heterogeneous catalyst for synthesizing diphenyl carbonate and preparation method thereof |
| abstract | The invention discloses a heterogeneous catalyst for synthesizing diphenyl carbonate and a preparation method thereof. The catalyst comprises a carrier, a titanium source and an organic acid. The mass ratio of the titanium source and the carrier is 10-70:90-30, and the titanium The molar ratio to organic acid is 0.05-5:1. The titanium source is tetrabutyl titanate, tetraisopropyl titanate, titanyl sulfate, titanocene dichloride, tetraethyl titanate, or biscyclopentadienyldimethyltitanium. The carrier is ZSM molecular sieve, HZSM molecular sieve, TS-1 molecular sieve, MCM-41 molecular sieve or SiO 2 . The organic acid is acetic acid, succinic acid, adipic acid, sebacic acid, terephthalic acid, benzoic acid or chlorosulfonic acid. During the specific preparation of the catalyst, 1) dissolving the titanium source in a solvent, then adding a carrier, performing a hydrothermal synthesis reaction at 80-120°C for 10-48 h, filtering, and drying the carrier to obtain a catalyst intermediate; 2) dissolving the catalyst intermediate In the solvent, drop an organic acid in an ice-water bath, stir at room temperature for 2-4 days, filter, wash and dry to obtain a catalyst. The catalyst has the characteristics of high activity and high selectivity. |
