Octene

Octene is an alkene with the formula C8H16. Several isomers of octene are known, depending on the position and the geometry of the double bond in the carbon chain.

The simplest isomer is 1-octene, an alpha-olefin used primarily as a co-monomer in production of polyethylene via the solution polymerization process. Several useful structural isomers of the octenes are obtained by dimerization of isobutene and 1-butene. These branched alkenes are used to alkylate phenols to give precursors to detergents.
