Definition

1. Noun:
   • A colorless flammable liquid alkane derived from petroleum and used as a solvent: "Hexane" is a specific hydrocarbon compound, a member of the alkane series, with the chemical formula C₆H₁₄. It is a volatile, flammable liquid obtained from petroleum refining and is commonly used as a solvent in laboratories and industrial processes.

Usage Examples

• Noun:
  • The laboratory uses hexane to extract oils from plant materials.
  • Hexane is a common component in some types of glue and adhesives.
  • Due to its flammability, hexane must be stored and handled with care.

Advanced Usage

• "n-hexane": This term specifies the normal (straight-chain) isomer of hexane, which is the most common and commercially significant form.
  • n-Hexane is often the specific solvent referred to in industrial safety guidelines.

Variants and Related Words

• Alkane (n): A saturated hydrocarbon with single bonds only, of which hexane is a member.
  • Methane, propane, and hexane are all alkanes.
• Isomer (n): Compounds with the same molecular formula but different structural arrangements. Hexane has several isomers.
  • Different isomers of hexane have slightly different chemical properties.
• Solvent (n): A substance that dissolves another substance. Hexane is classified as a non-polar solvent.
  • Hexane is an effective solvent for non-polar compounds like fats and waxes.

Synonyms

• Solvent: A substance, typically a liquid, used to dissolve other substances. (This is a functional synonym describing one of hexane's primary uses, not a chemical synonym.)
• Hydrocarbon: An organic compound consisting entirely of hydrogen and carbon. (This is a categorical synonym.)

Related Phrases and Technical Terms

• "Hexane fraction": Refers to a mixture of hydrocarbons, primarily hexane, obtained during the distillation of petroleum.
  • The hexane fraction is collected for use in solvent production.
• "Hexane extraction": A process that uses hexane as a solvent to separate oils or other compounds from a solid matrix.
  • Hexane extraction is a standard method for producing vegetable oils.
