摘　　要：综述了碳酸亚乙烯酯(VC)合成方法的研究进展,其制备过程主要有两步:(1)氯化反应:以碳酸乙烯酯作为原料进行氯代反应获得一氯代碳酸乙烯酯;(2)氯代碳酸乙烯酯进行脱氯反应得到VC粗品,经精馏、结晶纯化得到符合生产要求的VC成品。介绍了几种不同氯化剂、溶剂、脱卤化剂参与的合成工艺,为今后研究碳酸亚乙烯酯绿色合成方法提供理论依据。This study reviewed the research progress of vinylene carbonate(VC)synthesis.The preparation process mainly includes two steps.The first step Chlorination reaction:ethylene carbonate is a raw material to carry out chlorination reaction to obtain chlorinated ethylene carbonate.The second step:chlorinated ethylene carbonate is subjected to dechlorination to obtain a crude VC product,which is purified by rectification and crystallization to obtain a finished VC product that meets the production requirements.Several synthetic processes involving different chlorinating agents,solvents and dehalogenating agents were introduced,which provided a theoretical basis for future research on green synthetic methods of vinylene carbonate.
