摘　　要：一氯代碳酸亚乙酯在强极性溶剂碳酸亚乙酯溶剂中进行消除反应,合成了碳酸亚乙烯酯,反应产率为50%,反应时间从39h缩短为1h。利用红外光谱、质谱和氢核磁共振谱对产物进行了结构表征。Vinylene carbonate was synthesized by elimination reaction of monochloro-ethylene carbonate in a strong polar solvent ethylene carbonate. Under this condition, the yield of vinylene carbonate was 50 %, and the reaction time was dramatically reduced from 39 h to 1 h. The monochloro-ethylene carbonate and vinylene carbonate were characterized by FTIR, GC-MS and IHNMR respectively.
