Hexane is an open-chain, saturated hydrocarbon. It is a colorless, volatile, flammable liquid. It does not dissolve in water but dissolves well in alcohol, ether, petrol and benzene. Its combustion products are carbon-dioxide and water.

Cyclohexane can be produced from it by dehydrocyclation and hexene by dehydrogenation.

Occurrence and production

Hexane is a component of petrol, also produced from it by cracking.


It is used in the extraction of oils and fats, in the textile industry and for filling thermometers.
