    摘要: A dehydrogenation process for producing indene and substituted indenes from tetrahydroindene or substituted tetrahydroindene is described and comprises contacting said tetrahydroindene or substituted tetrahydroindene with a catalyst comprising cobalt oxide and molybdenum oxide at an elevated temperature for a period of from about 0.1 to 30 seconds. The tetrahydroindene and substituted tetrahydroindenes may be prepared from cyclopentadiene or dicyclopentadiene and a butadiene.

    摘要: 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.
