Baris 70:
Semasa digunakan sebagai bahan api kenderaan, propana dikenali sebagai [[gas petroleum cecair]] (LPG atau gas LP), yang mungkin sebagai campuran propana dengan bilangan kecil [[propylene]], [[butana]], dan [[butylene]]. Satu [[sebatian aroma|bahan berbau]] seperti [[ethanethiol]] atau [[thiophene]] ditambah supaya gas ini senang dihidu sekiranya terdapat kebocoran.
== Etimologi ==
Namanya dibentukkan daripada awalan "[[prop]]" (menandakan 3 atom karbon dalam rantai
== Sifat dan tindak balas ==
Propana mengalamai tindak balas [[pembakaran]] sama seperti alkana lain. Dalam kehadiran oksigen yang banyak, propana yang membakar membentuk [[air]] dan [[karbon dioksida]].
:C<sub>3</sub>H<sub>8</sub> + 5 O<sub>2</sub> → 3 CO<sub>2</sub> + 4 H<sub>2</sub>O + haba
Baris 87:
When properly combusted, propane produces about 50 MJ/kg.
The [[Higher Heating Value|gross heat of combustion]] of one [[normal cubic meter]] of propane is around 91 [[joule|megajoule]]
Propane is nontoxic; however, when abused as an inhalant it poses a mild [[asphyxia]]tion risk through [[oxygen]] deprivation. Commercial products contain hydrocarbons beyond propane, which may increase risk. Commonly stored under pressure at room temperature, propane and its mixtures expand and cool when released and may cause mild frostbite.
