重结晶法提纯碳酸亚乙烯酯的研究

Study on Purification of Vinylene Carbonate by Recrystallization Method

采用重结晶法对碳酸亚乙烯酯(VC)粗品进行提纯,考察了重结晶溶剂、溶剂用量、重结晶温度、恒温时间、重结晶次数对提纯效果的影响,并确定了最佳条件。研究结果表明:重结晶法提纯后VC纯度明显提高,且收率高。

Vinylene Carbonate（ VC） is purified by recrystallization method. The influence of solvent types and volume,temperature,holding time,recrystallization times on the purification effect are fully investigated,the optimum conditions are obtained. The results show that the purity of VC is obviously improved and the yield is high by recrystallization method.
