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. These isomers are flammable liquids. Decane is a component of gasoline (petrol) and kerosene. Like other alkanes, it is nonpolar solvent, does not dissolve in water, and is readily combustable. Although it is a component of fuels, it is of little importance as a chemical feedstock, unlike a handful of other alkanes.
Decane undergoes combustion, just like other alkanes. In the presence of sufficient oxygen, it burns to form water and carbon dioxide.
With insufficient oxygen, carbon monoxide is also formed.
It has a surface tension of 0.0238 N·m−1.
