1-Butene also known as 1-butylene, is an alkene with the chemical formula C4H8. It is a gaseous hydrocarbon with four carbon atoms and eight hydrogen atoms, featuring a double bond between the first and second carbon atoms. This unsaturated compound exists as two isomers, cis-1-butene and trans-1-butene, which differ in the spatial arrangement of their atoms.
Production of 1-Butene
1-Butene is primarily produced as a byproduct of crude oil refining and steam cracking processes. During these operations, larger hydrocarbons, such as butanes, undergo thermal cracking, leading to the formation of 1-butylene and other valuable compounds. Additionally, it can be obtained through catalytic dehydrogenation of butanes or through metathesis reactions.
