Propane is a three-caurbon alkane wi the molecular formula C
3H
8, normally a gas, but compressible tae a transportable liquid. A bi-product o naitural gas processin an petroleum refinin, it is commonly uised as a fuel for ingines, oxy-gas torches, barbecues, portable stoves, an residential central heatin. Propane is ane o a group o liquefied petroleum gases. The ithers include butane, propylene, butadiene, butylene, isobutylene an mixturs thareo.
Propane containin ower muckle propene (an aa called propylene) is nae suitit for maist vehicle fuels. HD-5 is a specification which establishes a maximum concentration o 5% propene in propane. Propane an ither LP gas specifications are established in ASTM D-1835.[5] Aw propane fuels include an odorant, almaist always ethanethiol, so that fowk can easily smell the gas in case o a leak. Propane as HD-5 wis oreeginally intendit for uise as vehicle fuel. HD-5 is currently bein uised in aw propane applications.
