Abstract: In a process for the production of perchloroethylene in an alumina-containing fluid bed reactor, the addition to the reaction gases, prior to an anhydrous quenching step, of a preferentially hydrochlorinatable ethylenically unsaturated chlorinated hydrocarbon reduces the tendency of the trichloroethylene also contained in the reaction gases to hydrochlorinate forming unsymmetrical tetrachloroethane.

Abstract: Organic epoxides in admixture with methylene chloride have been found to prevent degradation of methylene chloride in the presence of metals, metal halides, combinations thereof, and aromatic compounds, which react with methylene chloride in the presence of said metals, metal halides and combinations thereof. Reactions of aliphatic organic compounds with said metals, metal halides and combinations thereof to form products which result in deterioration of methylene chloride are also inhibited. A method for vapor degreasing metals by using the stabilized methylene chloride is described.
