[Chemical Properties]

Indane is a colourless to faintly yellow liquid. Insoluble in water, soluble in alcohol, ether and other organic solvents in any proportion.
[Application]

Indane is used as anti-vibration agent for aviation fuel and anti-vibration agent for rubber industry. Its derivatives can be used in pharmaceuticals and solvents. Indane can be cracked to produce benzene compounds.
[Definition]

ChEBI: Indane is an ortho-fused bicyclic hydrocarbon consisting of a benzene ring fused to a cyclopentane ring; a high-boiling (176°C) colourless liquid. It is a member of indanes and an ortho-fused bicyclic hydrocarbon.
[Preparation]

Taking heavy benzene with a Indan content of 35% as a raw material, rectifying it through an emulsification tower, and cutting the 182°C fraction from the top of the tower, that is, Indan with a content of more than 90%.?

[Hazard]

Irritant to skin and eyes.
[Synthesis]

3-phenyl-1-propene is isomerized to give indane in the presence of AlCl3:

Detected in distilled water-soluble fractions of 87 octane gasoline (0.40 mg/L), 94 octane gasoline (0.23 mg/L), Gasohol (0.50 mg/L), No. 2 fuel oil (0.05 mg/L), jet fuel A (0.15 mg/L), and diesel fuel (0.06 mg/L) (Potter, 1996). Based on laboratory analysis of 7 coal tar samples, indan concentrations ranged from ND to 3,800 ppm (EPRI, 1970).
[Environmental Fate]

Photolytic. Gas-phase reaction rate constants for OH radicals, NO3 radicals, and ozone at 24 °C were 1.9 x 10-11, 6.6 x 10-15, and <3 x 10-19 cm3/molecule?sec, respectively (Kwok et al., 1997).
[Purification Methods]

Shake indane with conc H2SO4, then water, dry and fractionally distil it. [Beilstein 5 H 486, 5 I 234, 5 II 376, 5 III 1200, 5 IV 1371.]
