Indan Chemical Properties,Uses,Production
Chemical Properties
Indane is a colourless to faintly yellow liquid. Insoluble in water, soluble in alcohol, ether and other organic solvents in any proportion.
Uses
Indane, is used as a catalytic agent, Petrochemical additive, used in organic synthesis. It is also used as pharmaceutical and chemical intermediate.
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.
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.
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:
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.]
