ABSTRACT:
A method of partially or totally separating C.sub.1 to C.sub.3 chlorinated aliphatic hydrocarbons from mixtures of at least two of such compounds; a liquid-liquid operation is carried out on such mixtures in the presence of one or more extraction agents having at least partial water-miscibility, the extraction agents being selected from the group of aprotic polar solvents, from the group of polyhydric alcohols, more particularly C.sub.2 to C.sub.7 saturated aliphatic polyhydric alcohols, C.sub.4 to C.sub.8 polyglycols, and glycol monoethers, more particularly C.sub.3 to C.sub.8 saturated aliphatic monoethers and the use of this process for the separation of mixtures comprising or essentially consisting of 1,2-dichloroethane and trichloroethylene.
