摘要：
The present invention provides an alkylene-carbonate synthesis catalyst comprising a compound insoluble to one phase containing alkylene carbonate produced when the alkylene oxide and carbon dioxide are reacted with the catalyst and soluble to the other phase substantially free of alkylene carbonate. The catalyst allows alkylene carbonate to be produced with high yield and selectivity and be readily collected. The catalyst also facilitates repeated or continuous reaction process in a cost-effective manner. The present invention also provides an apparatus for producing alkylene carbonate using the catalyst.
