Nonane or n-nonane is an organic chemical compound, a straight-chain hydrocarbon with the chemical formula C9H20. Unlike most alkanes, the numeric prefix in its name derives from Latin, rather than Greek (using a Greek prefix would be enneane).
Nonane will burn in air in the presence of an ignition source.
- C9H20 + 14 O2 → 9 CO2 + 10 H2O
Nonane is a colorless liquid, with a petroleum odor, insoluble in water, but miscible with other organic solvents.
Nonane can be extracted from various petroleum solvents, such as Stoddard solvent (which contains a mixture of aliphatic and alicyclic C7 to C12 hydrocarbons), via fractional distillation, though you need a large amount of Stoddard solvent to obtain any useful amount of n-nonane.
Nonane can also be purchased from chemical suppliers.
One way of obtaining (relative) pure nonane is through the decarboxylation of capric acid and its salts. However, this process will also give many side products and purification is required.
Nonane is best purchased than prepared.
- Organic extractions
Nonane vapors are irritant and because it's flammable, it is considered a fire hazard. However, as it is less volatile than most alkanes, its vapors are generally less of a problem.
In closed bottles, away from any heat source.
Nonane can be safely burned.
