Abstract

2-Chlorobutene-(2) is prepared by the dehydrochlorination of 2,2-dichlorobutane in the presence of a catalyst consisting of one or more of the metals Ca, Sr, Ba, Mg, Ni, Co, Fe, Zn, Cd and Cu and/or their chlorides and/or oxides and optionally a carrier, and the resulting 2-chlorobutene-(2) is purified by scrubbing with water and/or distillation. The dehydrochlorination is preferably effected at 50 DEG to 400 DEG C. optionally in the presence of an inert gas. Specified catalyst carriers are kaolin, kieselguhr, glass powder, porcelain, asbestos, pumice and active carbon.
