Description
GENERAL DESCRIPTION
N-pentanes are some of the primary blowing agents used in the
production of polystyrene foam and other foams. Usually, a mixture
of n-, i-, and increasingly cyclopentane is used for this purpose.
Because of its low boiling point, low cost, and relative safety,
pentane is used as a working medium in geothermal power stations.
It is added into some refrigerant blends as well.Â
N-pentanes are relatively inexpensive and are the most volatile
alkanes that are liquid at room temperature, so they are often used
in the laboratory as solvents that can be conveniently evaporated.
However, because of their nonpolarity and lack of functionality,
they can only dissolve non-polar and alkyl-rich compounds. Pentanes
are miscible with most common nonpolar solvents such as
chlorocarbons, aromatics, and ethers. They are also often used in
liquid chromatography.Â
