n-Hexane vs Hexane

What is the difference between hexane and n-Hexane?

Hexane is a general term for all structural isomers with the molecular formula C6H14. n-Hexane is the straight-chain isomer, consisting of six carbon atoms connected in a continuous chain.

Why are the terms sometimes used interchangeably?

In industry, “hexane” often refers to a mixture of isomers, usually containing a high proportion of n-Hexane. In scientific, contractual, or regulatory documents, “n-Hexane” is used to specify the exact compound and avoid ambiguity.

Do they have different physical properties?

n-Hexane has a boiling point of approximately 69 °C and a relatively narrow property range. Hexane mixtures have a broader boiling range, depending on the proportion of branched isomers.

How are they used in practice?

Hexane mixtures are commonly used in gasoline blending, solvents, adhesives, and cleaning agents. n-Hexane (pure) is widely used in vegetable oil extraction, laboratory solvents, and industrial cleaning.

How should they be specified in contracts or technical documents?

Use “n-Hexane” when referring to the straight-chain compound. Use “hexane” when referring to commercial solvent mixtures, but always include a specification sheet or certificate of analysis showing isomer composition. For clarity, include CAS number, purity level, and regulatory references where applicable.

Key Takeaway

Hexane is the umbrella term for all C6H14 isomers. n-Hexane is the straight-chain isomer, most relevant in industrial and regulatory contexts. Always distinguish between the two in technical or legal documents to ensure precision and compliance.
