Separation of liquids with different boiling points using a fractionating column, in which vaporisation and condensation occur repeatedly.
Revise: Separation of MixturesFractional distillation separates liquids with different boiling points. It is especially useful when their boiling points are relatively close, because simple distillation gives a less effective separation.
- Revise: Fractional Distillation
The separation of a mixture into fractions using differences in boiling point, through evaporation followed by condensation.
