摘　　要：以氯代碳酸乙烯酯为主原料、三乙胺为脱卤剂制备碳酸亚乙烯酯,系统考察了反应温度、反应物比例、溶剂体积、溶剂种类对反应时间的影响及不同溶剂对反应液抽滤效果的影响。研究结果表明:以碳酸丙烯酯为溶剂,合成反应时间最短,且抽滤分离效果最佳。Vinylene carbonate（VC） is prepared using chloroethylene carbonate as the main raw material and triethylamine as dehalogenation agent respectively. The influence of reaction temperature, ratios of reactants, solvent volume and types on the reaction time and the effects of different solvents on the filtration are fully investigated. The results show that using propylene carbonate （PC） as the solvent, the synthesis reaction time is the shortests the filtration and separation effect is the best.
