摘　　要：以碳酸乙烯酯（Ec）为原料，加入引发剂或光照条件下通人氯气反应合成氯代碳酸乙烯酯（CEC）。通过对反应时间、反应温度、引发剂的选择及用量、氯气流量等，考察了反应的进行状态和收率。通过气相色谱分析，在紫外光照和引发剂BPO联合使用，引发剂用量m（过氧化二苯甲酰）：m（CE）=0．3％，反应温度80～90℃，反应时间4h，n（C12）：n（EC）=1．2：1条件下，CEC收率为82．5oA。CEC was synthesized by substitution reaction from ethylene carbonate （EC） with chlorine （C12） as reagent, azobisisobutyronitrile （AIBN）, dibenzoyl peroxide （BPO） or UV-light as initiator. Based on different reaction conditions such as reaction time, reaction temperature, choice and dosage of initiator, flow rate of C12, etc. , the product yield was investigated respectively. The best condi- tions of the reaction between ethylene EC and C12 were controlled as that UV-light and BPO were used simultaneously, weight of substance ratio of BPO to EC was 0.3 ~, temperature was 80 - 90 ~C, reac- tion time was 4 h, and the amount of substance ratio of C12 to EC was n（C12） ＂ n（EC）=I. 2 ＂ 1. The Final product yield is 82.5 % By GC.
