decane
Very LowTechnical/Scientific
Definition
Meaning
A saturated hydrocarbon with the chemical formula C₁₀H₂₂, consisting of a chain of ten carbon atoms.
Any of the isomeric forms of this alkane, used as a reference in organic chemistry and as a component in fuels and solvents.
Linguistics
Semantic Notes
The term is part of the systematic nomenclature for alkanes (methane, ethane, propane...). It refers specifically to the straight-chain isomer (n-decane) unless otherwise specified. It is a colorless liquid at room temperature.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'декан' (dean of a university faculty). The chemical term is 'декан' in Russian, but the context makes the meaning clear.
Common Mistakes
- Mispronouncing it as /dɪˈkeɪn/ (like 'decade').
- Using it in general conversation where 'fuel' or 'chemical' would be more appropriate.
- Confusing it with other alkanes like 'octane' or 'dodecane'.

Frequently Asked Questions
Like many hydrocarbons, it is flammable and its vapours can be harmful if inhaled in large quantities. It should be handled with standard laboratory safety precautions.
It is primarily used as a solvent, a component in fuels, and a standard reference compound in chemical analysis and research.
Gasoline is a complex mixture of many different hydrocarbons, including some decane. Decane is a single, specific chemical compound.
Not as a pure substance. You might encounter it as a minor component in products like lighter fluid, certain solvents, or jet fuel, but it is not a household name.
