PROPANE

DOI: 10.1615/AtoZ.p.propane

Propane (C3H8) is a colorless and noncorrosive gas. It is highly flammable and at low concentration it forms an explosive mixture with air. Its main uses are as a feedstock in the production of ethylene, and as a solvent, refrigerant and aerosol propellant. Propane is the major constituent of liquefied petroleum gas (LPG) and as such it is increasingly stored in liquefied form at low temperatures in specially adapted natural underground caverns.
