Decene /dɛkiːn/ is an organic compound with the chemical formula C10H20. Decene contains a chain of ten carbon atoms with one double bond, making it an alkene. There are many isomers of decene depending on the position and geometry of the double bond. Dec-1-ene is the only isomer of industrial importance. As an alpha olefin, it is used as a comonomerincopolymers and is an intermediate in the production of epoxides, amines, oxo alcohols, synthetic lubricants, synthetic fatty acids and alkylated aromatics.[2]

The industrial processes used in the production of dec-1-ene are oligomerizationofethylene by the Ziegler process or by the cracking of petrochemical waxes.[3]
Inethenolysis, methyl oleate, the methyl esterofoleic acid, converts to 1-decene and methyl 9-decenoate:[4]
Dec-1-ene has been isolated from the leaves and rhizome of the plant Farfugium japonicum and has been detected as the initial product in the microbial degradation of n-decane.
