Hexane is an organic compound with a molecular formula of C6H14. It belongs to linear saturated aliphatic hydrocarbons. It is obtained from crude oil cracking and fractionation. It is a colorless liquid with a faint special odor. It is volatile, almost insoluble in water, and easily soluble in chloroform, ether, and ethanol. Mainly used as solvent, such as vegetable oil extraction solvent, propylene polymerization solvent, rubber and paint solvent, pigment diluent. It is used for the extraction of various edible oils such as soybeans, rice bran, cottonseeds, and oils in spices. In addition, the isomerization of n-hexane is one of the important processes for producing high-octane gasoline blending component.
