High vacuum distillation
WebApr 7, 2024 · 5.4A: Overview of Vacuum Distillation. Boiling commences when the vapor pressure of a liquid or solution equals the external or applied pressure (often atmospheric pressure). Thus, if the applied pressure is reduced, the boiling point of the liquid decreases (see the graph for cinnamyl alcohol in Figure 5.47a).
