摘要
以Cu粉为催化剂、N，N-二甲基甲酰胺（DMF）为溶剂、CCl4和2-氯丙烯为原料，进行调聚反应合成了1，1，1，3，3-五氯丁烷。考察了催化剂用量、反应压力、反应温度对合成反应的影响；同时研究了该合成反应的动力学。实验结果表明，适宜的1，1，1，3，3-五氯丁烷合成反应的条件为：催化剂用量0028mol，04MPa，373K，CCl40．878mol，2-氯丙烯0．595mol，DMF用量1．040mol。在此条件下采用假一级动力学方法确定，在353～393K内，1，1，1，3，3～五氯丁烷合成反应为二级反应，表观活化能为76，8kJ／mol，指数前因子为1，5×10^8，得到表观反应动力学方程。
1,1,1,3,3-pentachlorobutane was synthesized by telomerization from carbon tetrachloride and 2-chloropropene with copper powder as catalyst in dimethylformamide （DMF）. The effects of catalyst dosage, reaction pressure, and temperature on the synthesis were investigated and reaction kinetics of 1,1,1,3,3-pentachlorobutane synthesis was studied. The proper reaction conditions are： catalyst dosage 0. 028 mol, pressure 0.4 MPa, temperature 373 K, CC]4 dosage 0. 878 mol, 2-chloropropene dosage 0.595 mol and solvent DMF dosage 1. 040 mol. The telomerization is second-order reaction in ranges of 353 - 393 K by treating with pseudo-first-order method, the apparent activation energy is 76.8 kJ/mol, the pre-exponential factor is 1.5 × 10^8 and the apparent kinetic equation is obtained.
