ABSTRACT:
An improved process for preparation of 1,1,1-trichloroethane and/or vinylidene chloride by the direct high temperature chlorination of ethane, ethyl chloride, ethylene, 1,1-dichloroethane or mixtures thereof wherein the relatively small quantities of unsaturated, chlorinated compounds containing more than two carbon atoms formed as by-products are selectively reacted with elemental chlorine to produce stable compounds which are not detrimental to the efficient operation of subsequent iron catalyzed hydrochlorination and dehydrochlorination steps. This is accomplished in the presence of relatively high concentration of valuable unsaturated C.sub.2 's.
