Decane or n-decane is an organic chemical compound with the chemical formula C10H22. It is a straight-chain hydrocarbon, which appears as a thin liquid with a viscosity similar to water.

Properties

Chemical

Decane will burn in air in the presence of an ignition source, releasing carbon dioxide, water and soot.

Physical

Decane is a colorless liquid, insoluble in water, but miscible with other organic solvents. It has a very weak petroleum or bitumen-like smell. Decane boils at around 174 °C and freezes at −30 °C.

Availability

Decane 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-decane.

Complete reduction of caproic acid will yield n-decane.

Decane can also be purchased from chemical suppliers.

Preparation

Decane is best purchased or extracted from petroleum products than prepared.

Projects

  • Organic extractions

Handling

Safety

Decane is toxic if consumed, but generally it's quite harmless. Due to its high boiling point, it gives off few vapors, which may irritate the eyes on contact. Decane is flammable and will ignite in the presence of an ignition source.

Storage

Decane should be stored in closed bottles, away from any heat source. Due to its high boiling point, very little will evaporate over the years.

Disposal

Decane can be mixed with a more flammable solvent and safely burned outside.
