Distillation or rectification:
The distillation process separates several volatile liquids, simple or com‐ plex mixtures, by a series of vaporisation and condensation steps.
A number of liquids may be separated in this way if their boiling points are sufficiently different.
Continuous distillation separates a mixture into fractions: a volatile frac‐ tion, the distillate extracted at the column head and a heavy fraction, the residue extracted at the bottom of the column.
