Physical and chemical properties

  • It’s liquid
  • Colorless
  • Zero dipole moment
  • Boiling point of 35.95 ° C
  • Melting point of – 129.85 ° C

Reactions

Reaction with oxygen

5 H 12 + 8 O 2 → 5 CO 2 + 6 H 2 O

Reaction with halogens

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.

Obtaining

Pentane and its isomers are part of various oils and are obtained by fractional distillation.

Applications

  • 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.
