Abstract
A process for the co-production of indene and styrene from a mixture of cyclopentadiene or dicyclopentadiene and butadiene is disclosed. The process comprises the steps of reacting cyclopentadiene or dicyclopentadiene with butadiene in a Diels-Alder reaction to form a mixture of tetrahydroindene, vinylcyclohexene and vinylnorbornene followed by the recovery of the tetrahydroindene and vinylcyclohexene, and the oxydehydrogenation of the tetrahydroindene/vinylcyclohexene mixture utilizing a composite catalyst comprising cobalt oxide and molybdenum oxide.
