Hexane (C6H14) is a hydrocarbon extracted from crude oil. In fact, hexane is similar to the gasoline we put in our cars; it's just a slightly lighter molecule made of six carbon chains—compared to octane's eight. In its pure form, hexane is a colorless solvent that evaporates easily and dissolves only slightly in water.

The oil and hexane mixture is treated with steam to separate the hexane from the oil. Once the hexane is removed, it is recycled for additional processing. Hot air and cooling water are used in the final heating and drying of the oil. The crude soybean oil is degummed and may be deodorized, bleached, and neutralized.

Hexane, also called hexanes, is a mixture of straight-chain alkanes with six carbon atoms. It consists of approximately 60 percent n-hexane, varying amounts of the isomers 2-methylpentane and 3-methylpentane, and smaller amounts of non-isomer alkanes. Hexane is colorless and odorless when pure and has a boiling point of roughly 69°C (156°F).
