Butane is a colorless gas with a faint petroleum-like odor.
For transportation butane may be stenched.

Butane was discovered by the chemist Dr. Walter Snelling in 1912.
Butane was found dissolved in crude petroleum in 1864 by Edmund Ronalds, who was the first to describe its properties.

Butane is one of a group of liquefied petroleum gases (LP gases).
The others include propane, propylene, butadiene, butylene, isobutylene, and mixtures thereof.
Butane has a higher energy density and burns more cleanly than gasoline and coal.
Butane is registered under the REACH Regulation and is manufactured in and / or imported to the European Economic Area, at ≥ 1 000 000 to < 10 000 000 tonnes per annum.
Butane is used by consumers, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites and in manufacturing.

Butane [C4H10] is a colorless gas with a faint petroleum-like odor.
The main sources of butane are the refinery of crude oil and the processing of natural gas.
Butane is commonly blended into motor vehicle gasoline to increase the fuel’s volatility and to make engine starting easier.
Butane contains mixtures of methane, ethane, propane, isobutane, and butane and is a colourless aliphatic hydrocarbon gas with a gasoline-like odour.

Butane is a component of liquefied petroleum gas (LPG) and as such is used in a wide variety of fuel applications for both recreational and leisure use, including heating and air conditioning, refrigeration, cooking, and lighters.
Butane is commonly used alone or in mixtures as a propellant in aerosol consumer products, such as hairsprays, deodorants and antiperspirants, shaving creams, edible oil and dairy products, cleaners, pesticides, and coatings (e.g. automobile or household spray paint).

Butane is used as a chemical intermediate in the production of maleic anhydride, ethylene, methyl tert-butyl ether (MTBE), synthetic rubber, and acetic acid and its by-products.
Butane is a simple asphyxiant with explosive and flammable potential.
Butane is also a widely used substance of abuse.
The main target organs are in the CNS and cardiovascular system.
Improper use and handling cause poisoning.
Exposure to high levels of butane vapors can result in asphyxia.

USES
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.

For gasoline blending, butane is the main component used to manipulate the Reid vapor pressure (RVP).
Since winter fuels require much higher vapor pressure for engines to start, refineries raise the RVP by blending more butane into the fuel.
Butane has a relatively high research octane number (RON) and motor octane number (MON), which are 93 and 92 respectively.

When blended with propane and other hydrocarbons, the mixture may be referred to commercially as liquefied petroleum gas (LPG).
Butane is used as a petrol component, as a feedstock for the production of base petrochemicals in steam cracking, as fuel for cigarette lighters and as a propellant in aerosol sprays such as deodorants.

Pure forms of butane, especially isobutane, are used as refrigerants and have largely replaced the ozone-layer-depleting halomethanes in refrigerators, freezers, and air conditioning systems.
The operating pressure for butane is lower than for the halomethanes such as Freon-12 (R-12), so R-12 systems such as those in automotive air conditioning systems, when converted to pure butane, will function poorly.
A mixture of isobutane and propane is used instead to give cooling system performance comparable to use of R-12.

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.
The global market for butane canisters is dominated by South Korean manufacturers.

In the 20th century the Braun (company) of Germany made a cordless hair styling device product that used butane as its heat source to produce steam.

As fuel, butane is often mixed with small amounts of mercaptans to give the unburned gas an offensive smell easily detected by the human nose.
In this way, butane leaks can easily be identified.
While hydrogen sulfide and mercaptans are toxic, they are present in levels so low that suffocation and fire hazard by the butane becomes a concern far before toxicity.

Most commercially available butane also contains some contaminant oil, which can be removed by filtration and will otherwise leave a deposit at the point of ignition and may eventually block the uniform flow of gas.
The butane used as a solvent for fragrance extraction does not contain these contaminants and butane gas can cause gas explosions in poorly ventilated areas if leaks go unnoticed and are ignited by spark or flame.

Purified butane is used as a solvent in the industrial extraction of cannabis oils.
Butane is used in the following products: anti-freeze products, adhesives and sealants, fuels, polishes and waxes, air care products, washing & cleaning products, cosmetics and personal care products and adsorbents.

Other release to the environment of butane is likely to occur from: indoor use (e.g. machine wash liquids/detergents, automotive care products, paints and coating or adhesives, fragrances and air fresheners), indoor use in close systems with minimal release (e.g. cooling liquids in refrigerators, oil-based electric heaters), outdoor use in close systems with minimal release (e.g. hydraulic liquids in automotive suspension, lubricants in motor oil and break fluids) and outdoor use.

Butane can be used in the production of ethylene and 1,3-butadiene.
Butane can also be used as a chemical feedstock for special chemicals in the solvent, rubber, and plastics industries, in the blending of gasoline or motor fuel, as a constituent in liquefied petroleum gas [LPG], and as an extraction solvent in deasphalting processes.

Butane can be used for the manufacture of ethylene and butadiene, a key ingredient of synthetic rubber.
Butane [R600] is a kind of ozone depletion neutral refrigerant, being a potential refrigerant for household appliances.
