Use

Indene (also called 1H-Indene, C9H8) is a flammable polycyclic hydrocarbon. It is a colorless and aromatic smelling liquid. It is used in the synthesis of new C60 derivative (indene-C60 Bisadduct) and to prepare polyindene by the controlled cationic polymerization initiated with cumyl methyl ether/TiCl4 in CH2Cl2. Polyindene is further used to synthesize polyolefins. Indene is also used in the synthesis of istatins, in the production of indene/cumarone thermoplastic resins, and in the production of hydrocarbon resins. These industrial resins, also called indene-coumarone resins, are mainly consumed by the paints coatings, rubber, and construction industries. It should be stored in a cool place. The container should be kept tightly closed in a dry and well-ventilated place. Containers which areopened must be carefully resealed and kept upright to prevent leakage. Indene is incompatible with strong oxidizing agents. Recommended storage temperature is 2 - 8C. Indene is sensitive to light.
