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.[3] These isomers are flammable liquids. Decane is a component of gasoline (petrol) and kerosene.[4] 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.[5]
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.[6]
