Abstract: The telomerization reaction kinetics of 1,1,1,3- tetrachloropropane synthesis using tetrachloromethane and ethylene as raw materials was studied. The influence of catalyst concentration，pressure，temperature and other factors on the reaction was investigated by，using phosphate ester，powdered iron and FeCl3 as catalysts. It was found that the telomerization reaction was of first order and activation energy was 59.6 kJ/mol. A reaction kinetic equation was presented as follows：－rA= 6.566×107exp(－5.96×104／RT)CA0(1－xA)。
