isohexanes

Isohexanes are a group of branched-chain alkane isomers with the chemical formula C6H14. They are colorless liquids with a mild odor. The most common isomers include 2-methylpentane, 3-methylpentane, and 2,2-dimethylbutane. These hydrocarbons are derived from petroleum and are typically found as components of gasoline and petroleum ether.

In terms of physical properties, isohexanes are highly volatile and flammable. They are insoluble in water but soluble in most organic solvents. Their low boiling points make them useful in applications requiring rapid evaporation.

Isohexanes find widespread use as solvents in various industries. They are employed in the extraction of oils and fats, particularly in food processing for products like vegetable oils and protein isolates. They are also utilized as cleaning agents, degreasers, and as a diluent in paints, varnishes, and adhesives. In the pharmaceutical industry, they can be used in the purification of certain compounds. Due to their specific solvency characteristics, they are also found in some consumer products like aerosol propellants and some types of laboratory reagents. Their low toxicity, compared to some other organic solvents, contributes to their continued use in these applications.
