C9H8 A colorless, liquid, polynuclear hydrocarbon; boils at 181°C and freezes at -2°C; derived from coal tar distillates; copolymers with benzofuran have been manufactured on a small scale for use in coatings and floor coverings.



an aromatic hydrocarbon; a colorless liquid with a melting point of −2.6°C and a boiling point of 182.4 C. Indene is insoluble in water, is readily soluble in alcohol and ether, and polymerizes readily.

Small quantities of indene are contained in coal tar, from which it can be isolated easily; it is also found in petroleum and certain essential oils. Indene is primarily used for the preparation of coumarone-indene resins.
