2-Butene Chemical Properties,Usage,Production
Chemical Properties
2-butene appears as a colorless liquefied petroleum gas. Asphyxiate gas. Flammability limits in air 1.8-9.7% by volume.
Uses
2-Butene can be used as an intermediate, mainly for dehydrogenation to butadiene.
Definition
ChEBI: But-2-ene is a butene.
General Description
2-Butene is an alkene. All-silica zeolite RUB-41, containing 8- and 10-membered rings, is reported to be capable of separating trans-2-butene and cis-2-butene from 1-butene. Asymmetric gydrozirconation of cis- and trans-2-butene is reported. Stereospecific addition of methylene to trans-2-butene is reported to afford trans-1,2dimethylcyclopropane while similar addition to cis-2-butene affords cis-1,2dimethylcyclopropane.
Flammability and Explosibility
Extremely flammable
