An unsaturated halohydrocarbon such as vinylidene chloride is produced by the dehydrohalogenation of haloalkanes such as 1,1,1-trichloroethane or 1,1,2-trichloroethane, in the presence of a novel mixed salt catalyst containing a Group IA metal cation such as Cs, a Group IIA metal cation such as Mg and a neutralizing number of counter anions such as chloride distributed on a support such as silica. |
