| Hazard Information | Back Directory | [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%.? | [Synthesis Reference(s)]

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.] |
