Abstract
A process for the dehydrohalogenation of a feed comprised of an admixture of primary, secondary and tertiary alkylhalides to selectively convert the secondary and tertiary alkylhalides of the admixture to olefins by dehydrohalogenation, with minimal conversion, if any, of the primary alkylhalides. The reaction, which is particularly applicable to the selective dehydrobromination of an admixture of primary, secondary and tertiary alkylbromides, is carried out in a distillation-reaction zone, column, or distillation-reactor, to simultaneously (i) convert the secondary and tertiary alkylbromides to olefins and hydrogen bromide, and (ii) separate the olefins and hydrogen bromide, (iii) and the primary alkyl bromides, from the reaction mixture.
