But hexane fraction is any hydrocarbon that distills at close to the same temperature as n-hexane. This mostly means a mixture of other six-carbon hydrocarbons (e.g. 2-methylpentane) most of which boil between 55 and 70 °C. You might find that the mixture contains some C-7 hydrocarbons as well.
6) Commercial grades of hexane are used as solvents for glues (rubber cement, adhesives), varnishes, and. inks. ( 3,6) Hexane is also used as a cleaning agent (degreaser) in the printing industry. (
Common Uses for Hexane
Extracting edible oils from seeds and vegetables. As an additive in consumer products including gasoline, glue, varnishes and inks. As a cleaning agent in the textile, furniture and printing industries; As a special glue used in roofing, shoemaking and leather products.
n-hexane is also a structural isomer of hexane. Therefore, both these compounds have the same chemical formula and the same molar mass. The main difference between hexane and n-hexane is that hexane has 5 structural isomers that are either branched or unbranched structures whereas n-hexane is an unbranched structure.
Products where hexane is found
Common household products, such as spray adhesives, contact cement, arts and craft paints, and stain removers contain hexane.
