Vacuum distillation — Wikipedia Republished // WIKI 2

Vacuum distillation is a method of distillation performed under reduced pressure. 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 or will cause the compound to decompose. A reduced pressure decreases the boiling point of compounds. The reduction in .
