ABSTRACT:
A process for the continuous chlorination of ethylene in the liquid phase in the absence of light and in the presence of 1,2-dichloroethane and dissolved ferric chloride wherein the reaction is carried out in a homogeneous reaction zone in which the reaction medium contains dissolved chlorine in an amount within the range of 1 to 20 g per kg of liquid reaction mixture and in which the ratio R between the molar hourly flow rate of ethylene introduced to the homogeneous reaction zone and the molar hourly flow rate of ethylene which saturates the 1,2-dichloroethane contained in the reaction zone is within the range of 0 to 140.
