| titleOfInvention | Preparation method of epoxidation catalyst with high activity and low byproduct |
| abstract | The invention discloses a preparation method of a propylene or chloropropene liquid-phase epoxidation catalyst. The S auxiliary agent is added in the preparation process of the catalyst to obtain the titanium-rich TS-1 molecular sieve catalyst, amorphous species on the catalyst are stabilized by the S auxiliary agent, the decomposition of hydrogen peroxide can be reduced, and meanwhile, the introduced alkali metal ions reduce the acidity of the catalyst and can reduce the occurrence of side reactions, so that the high-activity low-byproduct epoxidation catalyst can be obtained. |
