Process for preparing styrene, and an appropriate agent

摘要

The invention relates to a process for oxidatively dehydrogenating dehydrogenatable organic compounds to prepare styrene. In this process, the compounds mentioned are reacted in the vapor phase with oxygen at a temperature above 350 DEG C. in the presence of a catalyst based on zirconium phosphate. Suitable dehydrogenatable organic compounds are above all saturated alkylaromatics, in particular ethylbenzene.
