氟代碳酸乙烯酯合成因素研究

Study on the Synthesis of Fluoroethylene Carbonate

以氯代碳酸乙烯酯(CEC)为原料,在有机溶剂中加入催化剂冠醚和氟化剂氟化钾反应生成氟代碳酸乙烯酯(FEC)。通过对原料氯代碳酸乙烯酯预处理、反应时间、反应温度、物料摩尔比等方面,考察合成反应的进行状态和收率,并在反应过程中取样检测、观察现象。通过气相色谱分析在最佳条件下反应收率为89.8%。

The fluoroethylene carbonate （FEC） was synthesized by substitution reaction of chloroethylene carbonate （CEC） with potassium fluoride （KF） as reagent, organic solvent as solvent, 18 - crown -6 as phase transfer catalyst. Based on different reaction conditions （such as CEC treatment, reaction time, reaction temperature etc. ）, the product yield was investigated respectively. The Final product yield is 89. 8% by GC.
