Abstract
1426677 Purification of vinyl chloride KANEGAFUCHI KAGAKU KOGYO KK 3 June 1974 [5 June 1973] 24446/74 Heading C2C A method of refining vinyl chloride monomer containing butadiene, such as is produced by the pyrolysis of ethylene dichloride, comprises mixing the monomer with chlorine and an organic substance that is easily chlorinated, and reacting the organic substance with the chlorine. The addition of the easily chlorinated organic substance suppresses the reaction of chlorine with vinyl chloride, the chlorine preferentially reacting with the butadiene. Organic substances which are easily chlorinated are those which have at least one unsaturated bond and which can form a high boiling point substance as a result of chlorination, e.g. chloroprene, butenes and monovinyl acetylene.
