摘　　要：以Fe0-FeCl3为催化剂,对四氯化碳与氯乙烯调聚合成1,1,1,3,3-五氯丙烷进行反应动力学研究。考察了催化剂用量、助催化剂用量和反应温度对反应速率和反应选择性的影响。结果表明,在四氯化碳过量,100～115℃下反应对催化剂是一级、对氯乙烯是零级,反应活化能为156kJ/mol;而反应的选择性则与催化剂用量成正比关系。动力学结果表明该反应遵循链式氧化还原机理。The telomerization of tetrachloromethane with chloroethylene promoted by Fe0-FeCl3 was subjected to detailed kinetic study.The influence of catalyst concentration,auxiliary catalyst,temperature on the reaction was investigated.It was found that the telomerization reaction was first order to catalyst and zero order to chloroethylene,and the reaction activity energy was 156 kJ/mol.The selective was proportioned to the concentration of catalyst.These data showed the proposal of a chain redox mechanism.
