isohexan

Isohexane, also known as 2-methylpentane, is a branched-chain alkane with the chemical formula C6H14. It is one of the six structural isomers of hexane. At standard temperature and pressure, isohexane is a colorless, volatile liquid with a gasoline-like odor. It is flammable and has a relatively low boiling point, around 60-62 degrees Celsius.

Isohexane is primarily obtained from petroleum refining processes, particularly through fractional distillation of crude oil. It is also a component of gasoline and is used as a solvent in various industrial applications. Its solvency properties make it useful in the extraction of oils, fats, and waxes, as well as in the production of adhesives and coatings. Additionally, it can be used as a reagent in organic synthesis. Due to its volatility, it evaporates quickly, which is advantageous in certain solvent applications.

In terms of safety, isohexane is considered moderately toxic. Inhalation of high concentrations of its vapor can cause dizziness, headache, and central nervous system depression. Prolonged or repeated skin contact can lead to defatting of the skin and dermatitis. It is important to handle isohexane in well-ventilated areas and to avoid sources of ignition due to its flammability. Environmental considerations include its potential to contribute to air pollution as a volatile organic compound (VOC).
