Abstract

Abstract: Technologies for the capture, storage and utilization of carbon dioxide, a major 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.

Key words: catalysis, ethylene oxide, ethylene carbonate, esterification, ionic liquid

摘要： 二氧化碳作为全球变暖的主要温室气体，用于其捕捉、存储和利用的技术具有很高的社会和经济价值。本文通过催化反应使环氧乙烷和二氧化碳环加成生成碳酸乙烯酯，在很温和的条件下，环氧乙烷转化率达到97%，碳酸乙烯酯选择性达到98%，在有效固定二氧化碳的同时制备高附加值的产品。本研究考察了季铵盐、鏻鎓盐、卤族金属盐、咪唑、吡啶类离子液体等催化剂在该反应中的催化性能；比较了温度、二氧化碳压力、转速、添加剂等条件对该反应的影响。
