Butane (/ ˈ b juː t eɪ n /) is an alkane with the formula C 4 H 10. Butane exists as two isomers, n -butane with connectivity CH 3 CH 2 CH 2 CH 3 and iso-butane with the formula (CH 3 ) 3 CH . Both isomers are highly flammable, colorless, easily liquefied gases that quickly vaporize at room temperature and pressure.

Liquefied petroleum gas, also referred to as liquid petroleum gas (LPG or LP gas), is a fuel gas which contains a flammable mixture of hydrocarbon gases, specifically propane, n-butane and isobutane. It can sometimes contain some propylene , butylene , and isobutene .

Propane and butane, easily liquified gases, are commonly known as liquified petroleum gas (LPG). [48] From pentane to octane the alkanes are highly volatile liquids. They are used as fuels in internal combustion engines , as they vaporize easily on entry into the combustion chamber without forming droplets, which would impair the uniformity of ...
The gas extracted from underground hydrocarbon deposits contains a varying mix of hydrocarbon components, which usually includes mostly methane (CH 4), along with ethane (C 2 H 6), propane (C 3 H 8) and butane (C 4 H 10). Other gases also occur in natural gas, notably CO 2. These gases have wide-ranging boiling points and also different heating ...
The natural gas condensate is also called condensate, or gas condensate, or sometimes natural gasoline because it contains hydrocarbons within the gasoline boiling range, and is also referred to by the shortened name condy by many workers on gas installations. Raw natural gas used to create condensate may come from any type of gas well such as ...
Isobutane, also known as i-butane, 2-methylpropane or methylpropane, is a chemical compound with molecular formula HC(CH 3) 3. It is an isomer of butane . Isobutane is a colorless, odorless gas.
