Hexane is an alkane with the chemical formula C6H14. As a hydrocarbon, it can undergo hydrocarbon combustion which gives off heat. Traces of hexane can be found in raw natural gas, which is a type of fossil fuel.[2] This hexane is usually removed before being shipped to customers as an energy currency.
Hexane is a volatile, colourless liquid that is highly flammable and insoluble in water.[3] Hexane has several important uses. Hexane is used frequently in the production and extraction of edible oils from nut and vegetable crops, such as soybeans and peanuts.[3]
This organic molecule also has several industrial uses. Primarily, when used in commercial grades, hexane is used as a solvent for glues and varnishes where water cannot be used. This works because hexane is a non-polar solvent while water is a polar solvent. It is also used as a cleaning agent known as a degreaser in the printing industry.[3]
Properties
Below is a table of some of the basic properties of hexane.
Chemical formula | C6H14 |
Molar mass | 86.17 grams/mole |
Melting point | -95oC[4] |
Boiling point | 69oC[4] |
Combustion Reaction
Hexane also undergoes hydrocarbon combustion, combining with oxygen to form carbon dioxide. The balanced chemical equation for the complete combustion of hexane is:
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.
