Butane is a gas at room temperature and atmospheric pressure. It is highly flammable, colorless, easily liquefied gases that quickly vaporize at room temperature.
Normal butane can be used for gasoline blending, as a fuel gas, fragrance extraction solvent, either alone or in a mixture with propane, and as a feedstock for the manufacture of ethylene and butadiene, a key ingredient of synthetic rubber. Isobutane is primarily used by refineries to enhance (increase) the octane number of motor gasoline.
Very pure forms of butane, especially isobutane, can be used as refrigerants and have largely replaced the ozone-layer-depleting halomethanes, for instance in household refrigerators and freezers. Butane is also used as lighter fuel for a common lighter or butane torch and is sold bottled as a fuel for cooking, barbecues and camping stoves.
As a food additive (E number 943A), butane is used as a propellant in aerosol spray cans for vegetable oil-based aerosol cooking sprays and water-based emulsion cooking sprays. It is also used as a propellant and aerating agent in foamed or sprayed food products. It is approved to use as food additive in EU.
