ABSTRACT:
This invention provides an improved oxydehydrogenation process for the production of tertiary-butylstyrene which involves the contacting of a vapor phase mixture of tertiarybutylethylbenzene and oxygen with a novel coprecipitated aluminum-calcium-silicon-tungsten phosphate catalyst composition.
The tertiary-butylstyrene is produced with a high conversion selectivity, and concomitantly there is little or no dialkenylbenzene byproduct produced.
