Isopentane

Formula: C5H12 or R601A

Isopentane is a colorless, flammable liquid with a mild gasoline odor.

Isopentane has a wide variety of uses. It is a major component in gasoline and is used as an energy transfer medium in geothermal power production. It is heated and then vaporizes to drive turbines.

Isopentane is used as a solvent capable of dissolving many organic compounds. It is also used as an aerosol propellant, replacing substances that are harmful to the ozone layer or have large greenhouse warming potentials.

Isopentane can also be used as a refrigerant, again replacing substances that are harmful to the ozone layer or have large greenhouse warming potentials. And isopentane is used as a foam blowing agent for producing expanded polystyrene.

It is used for cleaning of electronics.
