ABSTRACT:
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.
