Decane is an alkane with the chemical formula C10H22. As a type of hydrocarbon, it can undergo hydrocarbon combustion which gives off heat energy. Decane is a colourless liquid with a strong odour.[2] This organic molecule is a major component of diesel fuel and is also used in paint manufacturing as a hydrocarbon solvent.

Properties

Below is a table of some of the basic properties of decane.

Chemical formula C10H22
Molar mass 142.3 grams/mole
Energy density 44.2 MJ/kg [3]
Melting Point -30oC[4]
Boiling Point 174oC[4]

Combustion Reaction

Like all hydrocarbons, decane undergoes hydrocarbon combustion when used as a fuel. The balanced chemical equation for the complete combustion of decane is:

2 C10H22 + 31 O2 → 20 CO2 + 22 H2O + Heat Energy (Enthalpy)

The hydrocarbon combustion reaction releases heat energy and is an example of an exothermic reaction. The reaction also has a negative enthalpy change (ΔH) value.
