Abstract
This invention provides an improved oxydehydrogenation process for the production of tertiary-butylstyrene which involves the contacting of a vapor phase mixture of tertiary-butylethylbenzene and oxygen with a novel coprecipitated nickel-zirconium phosphate or nickel-zirconium-cerium phosphate catalyst composition. The tertiary-butylstyrene is produced with a high conversion selectivity, and concomitantly there is little or no dialkenylbenzene byproducts produced.
Claims5
A process for the production of tertiary-butylstyrene under moderate oxydehydrogenation conditions which comprises contacting a feed mixture of tertiary-butylethylbenzene and oxygen with a coprecipitated nickel-zirconium-cerium phosphate catalyst, wherein the cerium metal is in the plus three valence state, and the nickel, zirconium and cerium metal elements, respectively, are present in the catalyst in an atomic ratio of about 5-20:1:1 and the phosphate component is present in a sufficient quantity to satisfy the valences of the metal elements, and wherein the conversion selectivity to tertiary-butylstyrene is at least 80 mole percent, and the conversion selectivity to divinylbenzene is essentially zero mole percent.
