The distillation process separates several
volatile liquids, simple or complex 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 History of measures
into fractions: a volatile fraction, the distil-
late extracted at the column head and a
heavy fraction, the residue extracted at the
bottom of the column.
