Abstract
Tetrahydroindene is dehydrogenated in a vapor phase in the presence of a metallic catalyst, e.g., a nickel-molybdenum catalyst, to produce indene, which is industrially useful in high yield while inhibiting the catalyst from suffering a decrease in activity. In particular, a higher yield can be attained by a method in which tetrahydroindene is dehydrogenated to first convert it into indane, which is further dehydrogenated to obtain indene.
