Title: Process for separating ferric iron from chlorinated hydrocarbons

Abstract: Ferric iron is removed from chlorinated hydrocarbons having less than 6 carbon atoms per molecule by intimately contacting the latter with an oil that comprises one or more hydrocarbons having at least 6 concatenated aliphatic carbon atoms per molecule. The hydrocarbon oil is present in an amount sufficient to interact with a major portion of the ferric iron. The resulting mixture of the chlorinated hydrocarbon stream and the hydrocarbon oil is heated simultaneously with the intimate contacting, and a precipitate is allowed to form. The chlorinated hydrocarbon stream is then separated from the hydrocarbon oil and from the precipitate, and the precipitate is subsequently separated from the hydrocarbon oil, which may be recycled and re-used.
