Applications
Like all alkanes (paraffins, saturated hydrocarbons), n-octane is a very good solvent for nonpolar substances, fats and oils. Especially in the pharmaceutical industry, it is used as an inert solvent, for purification, recrystallization and washing of active pharmaceutical substances.
Heavy greases or oils can be diluted with paraffins such as n-octane to facilitate application. It is also found as a component in paints, varnishes and adhesives.
The technically most important octanes, n-octane and iso-octane, are used in special adhesives for plastics and elastomers (rubber) because they do not dissolve the plastic.
To separate liquid chemical products, it can help to add paraffins such as n-octane to the mixture. So-called azeotropes (mixtures that cannot be separated by distillation) can be separated in this way in many cases. This process is used especially in the production of elastane fibers (Spandex, Lycra).
