Vacuum distillation is a method of distillation performed under reduced pressure, which lowers the boiling point of most liquids. As with distillation, this technique separates compounds based on differences in boiling points. This technique is used when the boiling point of the desired compound is difficult to achieve, will cause the compound to decompose or simply to save energy in heating. A reduced pressure decreases the boiling point of compounds. The reduction in boiling point can be calculated using a temperature-pressure nomograph using the Clausius–Clapeyron relation.
