  2-Butene (107-01-7) is known as 3-01-00-00732 (Beilstein Handbook Reference) ; Butene, all isomers ; Butene-2 ; Butylene-2 ; CCRIS 8971 ; Dimethylethylene ; HSDB 180 ; Pseudobutylene ; beta-Butylene ; Butene, mixed -1- and -2- isomers . 2-Butene is an acyclic alkene which exists as two geometrical isomers (Z)-2-butene and (E)-2-butene . Both isomers behave similarly in the reactions. It is produced by the catalytic cracking of crude oil. 2-Butene (107-01-7) is mainly used in the production of gasoline , also used to produce the solvent butanone by hydration to 2-butanol followed by oxidation.
