ABSTRACT:
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, by contacting the haloalkane with a Group IA metal halide and a Group IIA or IIB metal oxide or metal hydroxide, together supported on a porous carrier material, under reaction conditions sufficient to form the corresponding unsaturated hydrocarbon and a Group IIA or IIB metal halide. The Group IIA or IIB metal oxide or metal hydroxide may be regenerated by contacting the Group IIA or IIB metal halide with an alkanol or water. In one embodiment, the process is initiated by contacting a novel catalyst comprising a Group IA metal cation such as Cs, a Group IIA or IIB metal cation such as Mg and a neutralizing number of halide anions such as chloride distributed on a support such as silica, with water or an alkanol under reaction conditions sufficient to form the Group IA metal halide and the Group IIA or IIB metal oxide or metal hydroxide supported on a porous carrier material. The process of the invention is also useful for the dehydrohalogenation of alkylene halohydrins to produce alkylene oxides. The process of the invention may be carried out in a riser reactor system, whereby the reactants are cycled in a continuous process.
