Products Description of Hexane CAS 110-54-3
Hexane is a straight-chain saturated aliphatic hydrocarbon with the chemical formula C₆H₁₄ and a molecular weight of 86.2. It appears as a colorless, volatile liquid with a distinctive gasoline-like scent.
Produced from crude oil via cracking and fractional distillation processes, it has a melting point of -95°C and a boiling point of 68.95°C, with a vapor density of 2.97 (relative to air = 1).
Nearly insoluble in water, hexane is highly soluble in organic solvents such as chloroform, ether, and ethanol. It is widely employed as an industrial solvent, playing a crucial role in the production of rubber, pharmaceuticals, perfumes, footwear, leather goods, textiles, furniture, and paints. Additionally, it is commonly used in adhesives and serves as an organic cleaning agent.
