Title:
CATALYST FOR SYNTHESIZING DIMETHYL CARBONATE BY MEANS OF METHANOL OXIDATIVE CARBONYLATION AND PREPARATION METHOD FOR AND APPLICATION OF CATALYST
Document Type and Number:
WIPO Patent Application WO/2023/193343
Kind Code:
A1
Abstract:
A catalyst for synthesizing dimethyl carbonate by means of methanol oxidative carbonylation and a preparation method for and an application of the catalyst. A carrier of the catalyst is a porous carbon-nitrogen material, and an active component is Cu; and the weight of Cu in the catalyst accounts for 5-15 wt% of the total weight of the catalyst. The catalyst has good catalytic activity in a reaction for synthesizing dimethyl carbonate by means of methanol oxidative carbonylation, has high space time yield and selectivity, and is easy to separate from a product.
