Abstract

1,2,3,4-Tetrachlorobutane having a predominant proportion of the solid isomer is prepared by reacting butadiene with chlorine in a solution of between 0.1 and 20% by weight of pyridine in an inert solvent. The solvent may be, for example, carbon tetrachloride or sym-tetrachloroethane but more conveniently is 1,2,3,4-tetrachlorobutane initially added to the reactants and supplemented by the liquid isomer and, if the reaction temperature is above 60 DEG C., the solid isomer product in the molten state. The solid isomer, which may be isolated from the reaction product by filtration, may be dehydrochlorinated to form 2,3-dichlorobutadiene.
