Vacuum distillation is distillation of liquids performed at a pressure lower than atmospheric pressure to take advantage of the fact that reducing the pressure lowers the boiling point of liquids. This permits the distillation of liquids that are temperature sensitive and avoids any degradation of such liquids.
