Fractional distillation is a process of separating two (or more) miscible liquids by distillation, the distillate being collected in fractions boiling at different temperatures.
The more volatile liquid (having lower boiling point) distils over first, and the less volatile liquid (having higher boiling point) distils over later.
A simple fractionating column is a tube packed with glass beads. The beads provide surface for the vapours to cool and condense repeatedly.
For example: - Mixture of acetone and water can be separated by fractional distillation.
