Pressure For Vacuum Distillation at Pam Cerys blog

Pressure For Vacuum Distillation. 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. Record the temperature over which material is collected, making sure the value corresponds to a temperature when the thermometer bulb is fully. In other words, distillation under reduced pressure is known as vacuum distillation. 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. A vacuum distillation is performed by applying a vacuum source to the vacuum adapter of either a simple or fractional distillation (figure 5.48). This is performed by lowering the pressures in the column or the reactor. When the pressure is lowered inside the apparatus, solutions boil at a lower temperature. A distillation operation that is performed at a pressure below atmospheric pressure is called vacuum distillation. Boiling commences when the vapor pressure of a liquid or solution equals the external or applied pressure.
