Hexane is a linear-chain saturated aliphatic hydrocarbon with molecular formula C6H14 and molecular weight 86.2. It appears as a colorless, volatile liquid with a typical gasoline‑like odor. Produced from crude oil via cracking and fractional distillation, hexane has a melting point of −95 °C and boiling point of 68.95 °C. Its vapor density is 2.97 relative to air.
Practically insoluble in water, hexane is highly soluble in organic solvents including chloroform, diethyl ether, and ethanol. As a widely used industrial solvent, hexane is essential in the production of rubber, pharmaceuticals, fragrances, footwear, leather, textiles, furniture, and coatings. It is also applied in adhesives and as an organic cleaning agent.
