Abstract

The gaseous mixture of hydrogen chloride and vinyl chloride, with or without other components, obtained in the cracking of ethylene dichloride after removal of unreacted ethylene dichloride, is treated with a liquid carbon chloride to dissolve out the vinyl chloride. The hydrogen chloride remaining may be reacted catalytically with acetylene to produce further vinyl chloride. Suitable solvents for the separation are CCl4, C2Cl4, hexachlorobutadiene and hexachlorocyclopentadiene, or a mixture thereof. Recovery of the vinyl chloride from the solution is described.ALSO:A gaseous mixture of hydrogen chloride and vinyl chloride, obtained in the cracking of ethylene dichloride after removal of unreacted ethylene dichloride, is treated with one or more liquid carbon chlorides, such as carbon tetrachloride, perchloroethylene, hexachlorobutadiene or hexachlorocyclopentadiene, to dissolve out the vinyl chloride.
