Title:
CATALYST FOR SYNTHESIZING CYCLIC CARBONATE AND SYNTHETIC METHOD FOR CYCLIC CARBONATE
Document Type and Number:
WIPO Patent Application WO/2024/001497
Kind Code:
A1
Abstract:
The present invention relates to the technical field of catalysis, in particular to a catalyst for synthesizing a cyclic carbonate and a synthetic method for a cyclic carbonate. The present invention provides a novel catalyst having a hydroxyl quaternary phosphonium salt structure. The catalytic effect of the catalyst is significantly improved by selecting a specific type of substituent groups, and the catalyst also has better stability. According to the cyclic carbonate synthesized by using the catalyst of the present invention, the product selectivity can be as high as 99.8%, and the yield can be as high as 99%; and the catalyst can be repeatedly used three or more times and still maintains a relatively high yield of the cyclic carbonate, and the catalyst has good stability.
