氟代碳酸乙烯酯的合成方法综述

综述了氟代碳酸乙烯酯的制备方法。其制备方法主要有两种:一、直接氟化法:以氟气、氮气和碳酸乙烯酯为原料在高温高压条件下的一步合成法;二、卤素交换法:碳酸乙烯酯先经过氯代反应生成氯代碳酸乙烯酯,然后与氟化试剂进行卤素取代反应制备氟代碳酸乙烯酯。并重点介绍了卤素取代反应中使用不同的催化剂用来合成氟代碳酸乙烯酯。

Synthetic Methods of Fluoroethylene Carbonate

In this paper,we reviewed the different preparation methods of fluoroethylene carbonate. There are two main different methods for the preparation. The first method is one - step process by using fluorine gas,nitrogen gas and ethylene carbonate as raw materials under conditions of high temperature and pressure. The second method contains two steps：chloroethylene carbonate is prepared by chlorination of the ethylene carbonate,and then the fluoroethylene carbonate is prepared by using the halogen - substitution reaction of chloroethylene carbonate with a fluorinating reagent. We also focus on the different catalysts used for synthesizing the fluoroethylene carbonate in the halogen - substitution reactions.
