Viscosity of Pentane


Pentane is an alkane of five carbon atoms, with the chemical formula C5H12. The term may refer to any of the three structural isomers with that formula, or to a mixture of them. In IUPAC nomenclature pentane is the unbranched isomer (n-pentane), the other two structures are named as methylbutane and dimethylpropane. Cyclopentane is not an isomer of pentane.

Pentanes are components of some fuels and are employed as specialty solvents in the laboratory. Their properties are very similar to those of butanes and hexanes.
