Distillation under reduced pressure (vacuum distillation) is generally used for the purification of high-boiling organic liquids that decompose at or below their normal boiling points.
In this method, the external pressure is reduced so that the liquid boils at a lower temperature than its normal boiling point. This prevents thermal decomposition and allows safe purification of heat-sensitive liquids such as glycerol, aniline, and nitrobenzene.
