Abstract
A process for preparing 1,1,1-trichloroethane from ethylene and chlorine by hydrochlorinating the ethylene in the presence of aluminum chloride in a liquid phase reaction zone followed by chlorination of the resulting reaction product and finally by hydrochlorination of the effluent from the chlorinator in the presence of ferric chloride. The principal product of this reaction is 1,1,1-trichloroethane. Numerous by-products and partially chlorinated and unsaturated chlorohydrocarbons are also produced but, in the major part, these are recyclable and produce, upon being recycled to the appropriate step, the precursors of or the desired 1,1,1-trichloroethane product.
