Physical and chemical properties
- It’s liquid
- Zero dipole moment
- Boiling point of 35.95 ° C
- Melting point of – 129.85 ° C
Reaction with oxygen
C 5 H 12 + 8 O 2 → 5 CO 2 + 6 H 2 O
Reaction with halogens
C 5 H 12 + Cl 2 → C 5 H 11 Cl + HCl
Such reactions are not selective; with n-pentane, the result is a mixture of 1-chloropentane, 2-chloropentane, and 3-chloropentane, as well as other more substituted chlorinated derivatives.
Pentane and its isomers are part of various oils and are obtained by fractional distillation.
- Production of Styrofoam.
- Gasoline production.
- It is used as a working medium in geothermal powerplants, due to its low boiling point.
- They are used in the laboratory as solvents since they evaporate easily.
- They are frequently used in liquid phase chromatography.
