Title:
CATALYST FOR REDUCTIVE AMINATION AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/056685
Kind Code:
A1
Abstract:
Provided is a catalyst for reductive amination and a preparation method therefor and the use thereof. The catalyst comprises a structure formed by a metal-based active center and a mercapto donor by means of a chemical bond, and the metal-based active center comprises a metal element selected from Group VIII. The catalyst for reductive amination may greatly improve the activity and selectivity of the catalyst to an organic amine product in an aldehyde/ketone-based reductive amination reaction, and a high selectivity can still be maintained under the condition that a small amount of ammonia water is used. In addition, the application batch stability of the catalyst is good, and the catalyst can be repeatedly used.
