摘　　要：运用结晶控制方法对工业级的碳酸亚乙烯酯(VC)进行提纯,对原料VC的主含量、结晶温度、降温速率、恒温时间及搅拌速度等控制晶型的重要影响因素进行了分析,并确定了最佳反应条件。通过研究,采用该法可得到主含量大于99.95%的高纯碳酸亚乙烯酯。Industrial vinylene carbonate （ VC ） was purified by crystallization control method. The crystal morphology influencing factors, such as crystal temperature, holding time, cooling rate, purity of raw material VC and stirring speed, etc. were analyzed and the optimum conditions of reaction were obtained. Vinylene carbonate with purity of more than 99.95% could be obtained by this method.
