Purification of Organic Compounds

We commonly use these methods for the purification of substances:

  • Simple crystallization - The most common method that we use to purify organic solids.
  • Fractional crystallization - It is the process of separation of different components of a mixture by repeated crystallisations.
  • Sublimation - Certain organic solids on heating directly change from solid to vapor state without passing through a liquid state. These substances are sublimable. This process is sublimation.
  • Simple distillation - It is the joint process of vaporization and condensation.
  • Fractional distillation - It is the process to separate a mixture of two or more miscible liquids which have boiling points close to each other
  • Distillation under reduced pressure
  • Steam distillation
  • Azeotropic distillation
  • Chromatography
