Formation of Dry Hydrogen Chloride by Means of Pyrolysis of the By-product of Vinyl Chloride Monomer Manufacturing

Abstract

A process is described for the pyrolysis of the by-products of vinyl chloride manufacture. By means of a batchwise combined gas-and liquid-phase pyrolysis at 1 atm about half of the chlorine present in the by-product could be recovered as dry hydrogen chloride, about 20% as vinyl chloride, and about 30% as chlorinated C2 hydrocarbons; less than 1 YO remained in the solid residue.
