Decane is an

nonpolar solvent, and 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.[8]

Reactions

Decane undergoes

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.

Physical properties

It has a surface tension of 0.0238 N·m−1.[9]
