The present invention relates to a novel catalyst system for chlorination of hydrocarbons either by oxyhydrochlorination, and/or oxychlorination. The catalyst system comprises copper chloride impregnated onto an alumina support with a metal chloride selected from the group consisting of potassium chloride, lithium chloride, cesium chloride, magnesium chloride, calcium chloride or barium chloride, said alumina support having a sodium oxide content of from 0. 2 to about 2. 0% by weight and a silica content no more than 4%.

Disclosed is a method of making phosphorous acid or hypophosphorous acid by reacting hydrogen chloride with a sodium phosphite or a sodium hypophosphite, respectively, in the presence of water to precipitate sodium chloride crystals and form the acid. The acid is separated from the sodium chloride crystals and can be passed through an anion exchange column that is preferably loaded with phosphite or hypophosphite ions, respectively, to remove residual chloride ions.

The present invention relates to a novel process of halogenating aliphatic hydrocarbons which comprises, first non-selectively oxyhalogenating a C. sub. 2 -C. sub. 6 aliphatic hydrocarbon to a partially halogenated intermediate product having an overall avarage empirical formula in which the atomic ratio of halogen to carbon is greater than 1:1, then vapor phase halogenating said intermediate product to form an end product having an atomic ratio of carbon to hydrogen is at least 2:1; thereby selectively coproducing or consuming hydrogen chloride.

The present invention relates to a novel catalyst for production of VCM containing a salt of rhodium or platinum, a salt of iron or copper, and a salt of zinc; impregnated on an alumina, titania, zirconia, silica, or silica alumina support. The catalyst can be employed in a fixed or fluid bed reactor to adiabatically produce vinyl chloride from a feed stream containing ethylene, a source of chlorine, a source of elemental oxygen, and, optionally, ethylene dichloride.
