hexane

[′hek‚sān]
(organic chemistry)
C6H14 Water-insoluble, toxic, flammable, colorless liquid with faint aroma; forms include: n-hexane, a straight-chain compound boiling at 68.7°C and used as a solvent, paint diluent, alcohol denaturant, and polymerization-reaction medium; isohexane, a mixture of hexane isomers boiling at 54-61°C and used as a solvent and freezing-point depressant; and neohexane.

Hexane

 

(n-hexane), the saturated hydrocarbon C6H14; a colorless liquid. Boiling point, 69°C; density, 0.660 g/cm3 (20°C); refractive index (Hexane), 1.37506.

In view of its low octane number (25), hexane is an undesirable constituent of synthetic gasoline. Hexane is present in considerable quantities in straight-run gasoline and in the cracking distillates of petroleum. Under the conditions of petroleum product aromatization and catalytic reforming, hexane is dehydrocyclized to benzene. The hexane isomers 2,2-dimethylbutane and 2,3-dimethylbutane (diisopropyl) are additives improving the quality of motor fuels.
