Abstract

A method of purifying trichloro-ethylene, b -trichlorethane, tetrachloroethane, perchlorethylene, ethylene dichloride, methylene chloride, chloroform or carbon tetrachloride comprises heating said liquid chlorinated hydrocarbon to a temperature of at least 70 DEG C. in the presence of anhydrous ferric chloride until liberation of hydrogen chloride and/or carbon dioxide ceases and then separating the purified chlorinated hydrocarbon from any reaction products and the ferric chloride residue. The chlorinated hydrocarbon may be washed after treatment with ferric chloride with water or a dilute aqueous alkaline solution, e.g. water containing triethylamine, the organic layer separated, steam distilled, dried and fractionated. Examples are furnished.
