Oxidative dehydrogenation of organic compounds in vapor phase with catalysts comprising crystalline compositions of iron, oxygen and at least one other metallic element. Preferred catalysts are ferrites.
Copper chloride has been employed as a reagent for oxychlorination of hydrocarbons. It has now been found that a non-halide copper compound in combination with a rare earth compound is an excellent oxychlorination catalyst, e.g. a CuCO.sub.3 - CeO.sub.2 catalyst calcined at 900.degree.

Selective catalysts and processes using same in which SO.sub.x compounds are reduced to elemental sulfur in oxidation-reduction processes in which simultaneously oxidizable gases undergo oxidation.
The yield in oxidative dehydrogenation of organic compounds is improved by having a surfur promoter present either as part of the catalyst or added to the reaction with the reactants.
