Title:
METHOD FOR CATALYTICALLY ACTIVATING CARBON DIOXIDE AS CARBONYLATION REAGENT WITH INORGANIC SULFUR
Document Type and Number:
WIPO Patent Application WO/2022/135355
Kind Code:
A1
Abstract:
Provided is a method for catalytically activating carbon dioxide as a carbonylation reagent with inorganic sulfur. In the method, carbon dioxide can be used to replace a toxic and harmful carbonylation reagent in the presence of H2S and an alkali for the synthesis of a carbonyl-containing fine chemical product. The method has a relatively high atomic economy and can reduce the generation of by-products.
