butene
Gaseous unsaturated hydrocarbon
Butene is a hydrocarbon gas with four carbon atoms and one double bond, making it an alkene.
Four structural variations (isomers) exist: 1-butene, 2-butene (in cis and trans forms), and isobutene.
Butene is used industrially to produce plastics, synthetic rubber, and gasoline additives.
Also called butylene.
