PROCESS FOR REDUCING THE AMOUNT OF TRICHLOROETHYLENE IN 1,2-DICHLOROETHANE

摘要

A process for converting trichloroethylene present in 1,2-dichloroethane by chlorination of the trichloroethylene in the liquid phase in the absence of light and in the presence of a Lewis acid catalyst wherein chlorine, 1,2-dichloroethane containing trichloroethylene and ethylene are introduced to a homogeneous reaction zone, with the mole ratio of ethylene to trichloroethylene being at least 50 and the mole ratio of trichloroethylene to chlorine being a maximum of 0.02.
