    Abstract: This invention relates to an unsaturated halohydrocarbon such as vinylidene chloride 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. The novel catalyst is highly selective, has high catalytic capacity and does not rapidly deactivate in typical dehydrohalogenation reactions when used in the presence of an alkanol and oxygen.

    Abstract: A thickened organic composition containing a first organophilic clay which will increase the viscosity of the composition and a second organophilic clay which is different from the first and which will impart biocidal activity to the composition. The second organophilic clay is the reaction product of a smectite-type clay and an organic cation having a benzyl group and a long chain alkyl group. The first and second organophilic clays can be mixed into the organic composition as and additive and may be prepared by using a mixture of cations.
