摘要
以碳酸乙烯酯和氯气为原料,在紫外灯引发条件下,合成氯代碳酸乙烯酯.考察光源功率、氯气流量和温度对光氯化反应的影响,并探究光氯化串联反应动力学.结果表明,实验最佳工艺条件为:单位体积输入功率为13.6 W/L的紫外灯,反应温度优选60℃,氯气流量范围500～750 mL/min.光氯化主副反应的表观活化能分别为7.98kJ/mol和11.37 kJ/mol.该动力学模型为后续多级串联反应器工业化设计提供了重要支撑.
Abstract
Using vinyl carbonate and chlorine gas as raw materials,chloroethylene carbonate is synthesized under the condition of UV lamp initiation.The effects of light source power,chlorine concentration and temperature on photochlorination reaction were investigated,and the photochlorination tandem reaction ki-netics were explored.The results show that the optimal process conditions for the experiment are:the input power per unit volume is 13.6 W/L UV lamp,the reaction temperature is preferably 60 ℃,and the chlo-rine flow range is 500～750 mL/mino The kinetics experimental results showed that the apparent activa-tion energy for photochlorination main and side reaction were 7.98 kJ/mol and 11.37 kJ/mol respective-ly.The residual error distributions and the statistic tests showed that the proposed kinetic models were reliable and adequate.
