Used as a propellant or aerosol in cosmetics. The principal hazard is that of fire and explosion, but it may be narcotic in high doses and cause asphyxiation.

C4H10, a colorless gas used in petrochemical synthesis and bottled gas.

A hydrocarbon gas found in the earth along with natural gas and oil. Butane turns into a liquid when put under pressure. It is sold as bottled gas. It is used to run heaters, stoves and motors, and to help make petrochemicals.

A normally gaseous paraffin compound having the chemical formula of C4H10.

The saturated hydrocarbon (alkane) with four carbon atoms in its molecule. The fourth member of the paraffin series. A gas at atmospheric pressure and normal temperature, but easily liquefied by pressure for transportation and subsequent use.

A low-boiling paraffin hydrocarbon generally stored and delivered in liquefied form and used as a fuel in gaseous form, obtained by processing natural gas as produced and also from a process in petroleum refining. Contains approximately 3,260 Btu per cubic foot.

A hydrocarbon associated with petroleum. It is gaseous at ordinary atmospheric conditions.

A liquified petroleum gas normally stored under pressure in a gas bottle. The colour of the bottle is usually blue. This form of LPG is useful for barbecues and other summer activities. Not normally used on narrowboats as the liquid ceases to gas at temperatures close to freezing and thus fails to operate any units connected to the system.

refers usually to a mixture of isobutane and normal butane. A flammable, gaseous hydrocarbon. Used as fuel.

A fuel gas having the formula C4H10. A constituent of LP gas. One pound of liquid butane produces 6.4 cubic feet of gas. One gallon of liquid butane weighs 4.87 pounds and produces 31 cubic feet of gas. One cubic foot of butane gas produces 3266 BTUs.

occurs in natural gas; used in the manufacture of rubber and fuels

A hydrocarbon gas that is one of the ingredients in natural gas. Butane molecules consist of four carbon atoms and ten hydrogen atoms.

A colourless, odourless, non-toxic gas; not generally used in hearth.

Either of two saturated hydrocarbons, or alkanes, with chemical formula. In both compounds carbon atoms are joined in an open chain.

A gaseous hydrocarbon of the alkane series (C4H10).

A normally gaseous hydrocarbon which is extracted from natural gas or refinery gas streams. It is used as household fuel, propellant and refrigerant.

A component of natural gas consisting of four carbon atoms and 10 hydrogen atoms; condenses into a liquid at relatively low temperature and pressure

(C4H10) - gaseous organic compound containing only carbon and hydrogen. Each molecule contains a chain of four carbon atoms.

A gas, easily liquefied, recovered from natural gas. Used as a low-volatility component of motor gasoline, processed further for a high-octane gasoline component, used in LPG for domestic and industrial applications and used as a raw material for petrochemical synthesis.

A light hydrocarbon gaseous at normal room temperature but can be liquefied under moderate pressure. Has a boiling point of about 2oC. Sold by Calor Gas Ltd in Blue cylinders

Either of two isomeric, flammable, gaseous hydrocarbons, C4H10, of the paraffin series n-butane or isobutane.

An aerosol propellant that is not harmful to the earth's ozone layer.

Gas usually in blue bottles. Most commonly used by UK motorcaravanners, although many switch to propane in severely cold weather conditions

Aerosol propellant. Flammable and in high doses may be narcotic or cause asphyxiation.

Butane, also called n-butane, is the unbranched alkane with four carbon atoms, CH3CH2CH2CH3. Butane is also used as a collective term for n-butane together with its only other isomer, isobutane (also called methylpropane), CH(CH3)3.
