 |  | 2-Butene Usage And Synthesis |  
 | 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 | Extremelyflammable |
