Indene, also known as benzocyclopropylene, is a kind of polycyclic aromatic hydrocarbon, low toxicity, irritating to human skin and mucosa. Naturally occurring in coal tar and crude oil, in addition to the incomplete combustion of fossil fuels, will also release indene. Molecular formula C9H8. Molecular weight 116.16. The benzene ring and cyclopentadiene share two adjacent carbon atoms in their molecules. It is a colorless liquid, which is not volatile in vapor and turns yellow when standing, but loses its color when exposed to sunlight. The melting point is - 1.8 C, the boiling point is 182.6 C, the flash point is 58 C, and the relative density is 0.9960 (25/4 C). It is insoluble in water and can be mixed with ethanol or ether. The enene molecules contain highly active olefinic bonds and are prone to polymerization or addition reactions.

Except for a small amount of organic solvents and insecticides, it is mainly used for the production of Malone resin. The raw material of indene-gumalone resin is the distillation of heavy benzene and light oil at 160-215 C, which contains about 6% styrene, 4% gumalone, 40% indene, 5% 4-methylstyrene and a small amount of xylene, toluene and other compounds. The total amount of resin accounts for 60-70% of the raw material. In the presence of aluminium chloride, boron fluoride or concentrated sulfuric acid, the indene and coumarone fractions are polymerized under pressure or without pressure to form indene-coumarone resin.
