Pentane is an organic compound that comes in a colorless liquid and is naturally volatile with a gas-like odor. It is an alkane with five carbon atoms and can refer to any of three structural isomers, or to a mixture of them. Pentane has several uses, including:
-
Solvent: Pentanes are the most volatile liquid alkanes at room temperature and are often used in the laboratory as solvents that can be conveniently and rapidly evaporated.
-
Chromatography: Pentane is commonly used in chromatography, which is a laboratory technique to separate components in a mixture.
-
Blowing Agent: Pentane is used as the primary blowing agent in the production of foams like polystyrene. These foams are often used as insulating material in refrigerators and heating pipes.
-
Working Medium: Because of its low boiling point, pentane is used in geothermal power stations as a binary fluid. It is also used as a working medium in organic Rankine cycles.
-
Personal Care Products: Very pure, aromatic-free iso-Pentane is used in shaving cream or shower gel from cans, as it evaporates through body temperature and makes the products foam up very finely and creamy.
-
Industrial Ingredient Uses: Pentane is used in making other chemicals, plastics, and low-grade thermometers. It is also a constituent in motor and aviation fuel, in solvent extraction processes, and as a medium solvent for polymerization reactions.
It is important to note that pentane is a flammable liquid and can form an ignitable vapor/air mixture in closed tanks or containers. It may react violently with oxidizing agents to cause fires and explosions.
