But-2-ene is an acyclic alkene with four carbon atoms. It is the simplest alkene exhibiting cis/trans-isomerism (also known as (E/Z)-isomerism); that is, it exists as two geometric isomers cis-but-2-ene ((Z)-but-2-ene) and trans-but-2-ene ((E)-but-2-ene). It is a petrochemical, produced by the catalytic cracking of crude oil or the dimerization ...

Butene, also known as butylene, is an alkene with the formula C 4 H 8. The word butene may refer to any of the individual compounds. They are colourless gases that are present in crude oil as a minor constituent in quantities that are too small for viable extraction.

All four butenes are gases at room temperature and pressure. …alkenes, two versions of 2-butene exist. They are traditionally called cis -2-butene and trans -2-butene or, in slightly more modern terms, (Z)- and (E)-2-butene. The Z and E stand for the German words for “together” (zusammen) and “apart” (entgegen).

2-Butene is an isomeric mixture of trans-and cis-2-butene recovered from refining gases or produced by petroleum cracking(2). 2-Butene occurs in coal gas and has been detected in diesel exhaust(2). 2-Butene has been identified as a constituent of tobacco smoke(3).

butene, any of four isomeric compounds belonging to the series of olefinic hydrocarbons. The chemical formula is C 4 H 8. The isomeric forms are 1-butene, cis - 2-butene, trans -2-butene, and isobutylene. All four butenes are gases at room temperature and pressure.
