The n-hexane alias hexane, molecular formula C 6 H 14, has a molecular weight of 86.2, and belongs to linear saturated aliphatic hydrocarbons, which are obtained by cracking and fractionating crude oil. Appearance is colorless with gasoline smell, volatile liquid, melting point (MP) is 95 ° C, boiling point is 68.95 ° C, vapor density is 2.97 (air = 1), almost insoluble in water, soluble in chloroform, ether, ethanol . N-hexane is an organic solvent and is commonly used in rubber, pharmaceutical, perfume, shoemaking, leather, textile, furniture, paint and other production processes. In recent years, n-hexane has been used as a diluent for the production of adhesives, or as an organic cleaning agent, and has become the culprit of occupational hexane poisoning in China.
