摘要
Abstract
Technologies for the capture,storage and utilization of carbon dioxide,a maj or green house gas that causes global warming,are of great economic and social benefits.This work studied the catalytic cycloaddition/esterification reaction of ethylene oxide and carbon dioxide to produce ethylene carbonate,a process that served to fix carbon dioxide as well as produce value added ethylene carbonate product.The conversion of ethylene oxide reached 97% and the selectivity to ethylene carbonate reached 98% under very mild conditions.We studied various catalysts for this reaction such as quaternary ammonium salts,quaternary phosphonium salt, metal halides,imidazole and pyridine based ionic liquids and etc.The effect of reaction conditions such as temperature,carbon dioxide pressure,stirring rate and co-catalyst were also studied.关键词
