Quick Summary

1-butene is one of four isomeric compounds in the butene series of olefinic hydrocarbons, with the chemical formula C4H8. The other isomers are cis-2-butene, trans-2-butene, and isobutylene. All butenes are gases at room temperature and pressure.1

Butenes are produced during petroleum cracking and can be made commercially by dehydrogenating butanes. They are primarily used to produce octanes for gasoline, either by reacting with isobutane or by dimerizing to form octenes, which are then hydrogenated to octanes. Butenes can also be converted into butyl alcohols, used as solvents, or dehydrogenated to form butadiene, a key component in synthetic rubber production.1
