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 aluminum-calcium-cerium phosphate catalyst composition. The tertiary-butylstyrene is produced with a high conversion selectivity, and concomitantly there is little or no dialkenylbenzene byproducts produced.
Claims3
A coprecipitated catalyst composition adapted for oxydehydrogenation reactions, which catalyst composition corresponds to the formula:
- Al.sub.5-20 Ca.sub.5-20 Ce.sub.1 (PO.sub.4).sub.x
- wherein x is a number sufficient to satisfy the valences of the metal elements in the catalyst.
