Decaneis analkanehydrocarbonwith thechemical formulaC10H22.Although 75 structuralisomersare 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 areflammableliquids.Decane is present in small quantities (less than 1%) ingasoline(petrol) andkerosene.[6][7]Like other alkanes, it is anonpolarsolvent, and does not dissolve inwater,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.[8]
Reactions[edit]
Decane undergoescombustion,just like otheralkanes.In the presence of sufficient oxygen, it burns to formwaterandcarbon dioxide.
- 2 C10H22+ 31 O2→ 20 CO2+ 22 H2O
With insufficient oxygen,carbon monoxideis also formed.
Physical properties[edit]
It has a surface tension of 0.0238 N·m−1.[9]
