Molecule Structure Image



Pentane is an alkane with five carbon atoms. It is one of the primary blowing agents used in the production of polystyrene foam. 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. It is used in the laboratory as solvents and also often used in liquid chromatography.
