Decane is an alkane hydrocarbon with the chemical formula C₁₀H₂₂. Although 75 structural isomers are possible for decane, the term usually refers to the normal-decane ("n-decane"), with the formula CH₃(CH₂)₈CH₃. All isomers, however, exhibit similar properties and little attention is paid to the composition.^[5] These isomers are flammable liquids. Decane is a component of gasoline (petrol) and kerosene.^[6] Like other alkanes, it is a nonpolar solvent, does not dissolve in water, and is readily combustible. Although it is a component of fuels, it is of little importance as a chemical feedstock, unlike a handful of other alkanes.^[7]

Reactions[]

Decane undergoes combustion, just like other alkanes. In the presence of sufficient oxygen, it burns to form water and carbon dioxide.

2 C₁₀H₂₂ + 31 O₂ → 20 CO₂ + 22 H₂O

With insufficient oxygen, carbon monoxide is also formed.

Other[]

It has a surface tension of 0.0238 N·m⁻¹.^[8]
