Why Is Vacuum Distillation Used at Eddie Hutto blog

Why Is Vacuum Distillation Used. A vacuum distillation is used when the boiling point of the compound (or the solvent) is too high (t>150 o c) in order to distill the compound (or the solvent off) without significant decomposition. A vacuum distillation is performed by applying a vacuum source to the vacuum adapter of either a simple or fractional distillation (figure 5.48). Vacuum distillation is a method of distillation whereby the pressure above the liquid mixture to be distilled is reduced to less than its vapor pressure. Vacuum distillation is a technique for the purification or separation of liquids or solvents with a boiling point above 150 ºc, or with a lower. Boiling commences when the vapor pressure of a liquid or solution equals the external or applied pressure. A fraction distillation can also be used. It is assumed that readers have previously performed a simple distillation under atmospheric pressure, so in this section are described differences between atmospheric and reduced. A vacuum distillation apparatus is shown in figure 5.50, using a simple distillation setup. When the pressure is lowered inside the apparatus, solutions boil at a lower temperature.
