Abstract
A continuous process for chlorination of 1,1,1-trichloroethane alone or in admixture with other aliphatic chlorinated C.sub.1 to C.sub.4 hydrocarbons in a liquid phase reaction with molecular chlorine in the presence of a catalyst selected from the group consisting of ferric chloride, iron oxychloride and mixtures thereof in the absence of light radiations wherein the reaction may be carried out in a single reaction zone at a temperature within the range of 35.degree.-120.degree. C. or in a series of reaction zones in which the effluent from the first reaction zone is introduced into the second reaction zone along with additional chlorine and unsaturated chlorinated hydrocarbon with the temperature in the second reaction zone being less by at least 5.degree. than the temperature in the initial reaction zone.
