Title:
CATALYST FOR PHOSGENATION REACTION AND PHOSGENATION REACTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/143194
Kind Code:
A1
Abstract:
The present invention relates to a catalyst for a phosgenation reaction and a phosgenation reaction method. The catalyst for a phosgenation reaction of the present invention is a phosphinyl ionic liquid as represented by general formula (I). In addition, the phosgenation reaction method provided by the present invention is a phosgenation reaction method using phosgene as a chlorination agent, and in the phosgenation reaction method, the catalyst for a phosgenation reaction as provided by the present invention is used. Compared with the use of the catalyst of triphenylphosphine oxide, etc., in a phosgenation reaction, the catalyst provided by the present invention can result in the charge rate of phosgene in a phosgenation reaction being reduced and the reaction time being shortened, thereby indicating a higher reaction efficiency and a higher atomic utilization of phosgene.
