Title:
CATALYST MODIFIED WITH THIOL LIGAND, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/012005
Kind Code:
A1
Abstract:
The present invention provides a catalyst modified with a thiol ligand, a preparation method therefor and use thereof. The method comprises: introducing a hydrogen-containing gas, and modifying Pd4S or Pd4S/X by a thiol ligand under a gas atmosphere, so as to prepare and obtain an M-Pd4S catalyst or an M-Pd4S/X catalyst with a carrier. The catalyst prepared by the present invention achieves high selectivity for an intermediate alkyne compound in a semi-hydrogenation reaction of alkyne; in addition, the preparation method for the catalyst of the present invention has simple operation and universality.
