Hexane?(/?h?kse?n/) is an?organic compound, a straight-chain?alkane?with six?carbon?atoms and has the?molecular formula?C6H14.
It is a colorless liquid, odorless when pure, and with boiling points approximately 69?°C (156?°F). It is widely used as a cheap, relatively safe, largely unreactive, and easily evaporated?non-polar solvent, and modern?gasoline?blends contain about 3% hexane.
The term?hexanes?refers to a?mixture, composed largely (>60%) of hexane, with varying amounts of the isomeric compounds?2-methylpentane?and?3-methylpentane, and, possibly, smaller amounts of nonisomeric C5, C6, and C7?(cyclo)alkanes. These?hexanes?are cheaper than pure hexane and are often used in large-scale operations not requiring a single?isomer?(e.g., as?cleaning solvent?or for?chromatography).

Uses
In industry, hexanes are used in the formulation of?glues?for shoes,?leather?products, and roofing. They are also used to extract?cooking oils?(such as?canola oil?or soy oil) from seeds, for cleansing and?degreasing?a variety of items, and in textile manufacturing. They are commonly used in food based?soybean oil?extraction in the United States, and are potentially present as contaminants in all soy food products in which the technique is used; the lack of regulation by the?FDA?of this contaminant is a matter of some controversy.
A typical laboratory use of hexanes is to extract?oil?and?grease?contaminants from water and soil for analysis.Since hexane cannot be easily?deprotonated, it is used in the laboratory for reactions that involve very strong bases, such as the preparation of?organolithiums. For example, butyllithiums are typically supplied as a hexane solution.
Hexanes are commonly used in?chromatography?as a non-polar solvent. Higher alkanes present as impurities in hexanes have similar retention times as the solvent, meaning that fractions containing hexane will also contain these impurities. In preparative chromatography, concentration of a large volume of hexanes can result in a sample that is appreciably contaminated by alkanes. This may result in a solid compound being obtained as an?oil?and the alkanes may interfere with analysis.
