Propane

CAS No.: 74-98-6

Molecular formula: C3H8

Other Names: Propane

Propane is a three-carbon alkane with the molecular formula C3H8, normally a gas, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel for engines, oxy-gas torches, barbecues, portable stoves and residential central heating. Propane is one of a group of liquefied petroleum gases (LP gases). The others include butane, propylene, butadiene, butylene, isobutylene and mixtures thereof.

Propane is mainly used as:

• Mixed refrigerant,

• Fuels,

• Propellant,

• Food additives,

• The raw materials for the production of propylene and solvents.
