<p>A process for the production of 2,3-dichlorobutadiene- (1,3) 2,3-Dichlorobutadiene-(1,3) is obtained from 2,3,4-trichlorobutene-1 by dehydrohalogenation in the presence of a phase transfer catalyst, an inhibitor and oxygen according to an improved process in which the aqueous solution of an alkali metal hydroxide is added to the mixture of trichlorobutene, catalyst, inhibitor and optionally water, and the reaction is carried out at a temperature of from -10 to +60.degree.C under an inert gas which contains from 0.1 to 8 % by weight of oxygen.</p> |
