Hydrochlorination of 1,3-butadiene

Hydrochlorination of 1,3-Butadiene. A historic process for the synthesis of adi-ponitrile was the transformation of 1,3-butadiene through 1,4-dichlorobutene.187 Addition of HC1 was carried out in the vapor phase (125-230° C) in an excess of 1,3-butadiene. A mixture of isomeric dichlorobutenes (3,4-dichloro-l-butene, cis-and trans-l,4-dichloro-2-butene) was formed. They underwent further transformations to form the dicyanides and then, after hydrogenation, to give adiponitrile.
