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 comonomer in copolymers 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 oligomerization of ethylene by the Ziegler process or by the cracking of petrochemical waxes.^[3]

In ethenolysis, methyl oleate, the methyl ester of oleic acid, converts to 1-decene and methyl 9-decenoate:^[4]

${\displaystyle {\overset {\text{methyl oleate}}{{\ce {CH3(CH2)7CH=CH(CH2)7CO2Me}}}}+{\color {red}{\ce {CH2=CH2}}}\longrightarrow {\overset {\text{1-decene}}{{\ce {CH3(CH2)7CH=}}{\color {red}{\ce {CH2}}}}}+{\overset {\text{9-decenoate}}{{\ce {MeO2C(CH2)7CH=}}{\color {red}{\ce {CH2}}}}}}$

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.
