Mar 05, 2021 5.4: Vacuum Distillation ... The preferred method for solvent removal in the laboratory is by use of a rotary evaporator (also known as a rotovap ), A rotary evaporator is essentially a reduced pressure distillation: a solution in a round bottomed flask is placed in the water bath of the apparatus, and rotated while the system is partially ...

pump on the flask for 30 minutes. If your compound is volatile—low molecular weight and/or low boiling point—obtain a constant weight using the rotovap, not the vacuum pump. 13) Obtain a constant weight. Weigh the flask after leaving it on the vacuum pump (or rotovap), then return to the pump (or rotovap) for 15 to 30 minutes and weigh again.

Vacuum distillation - Wikipedia

Vacuum distillation - Wikipedia

Vacuum distillation is distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in their boiling points. This technique is used when the boiling point of the desired compound is difficult to achieve or will …

Vacuum towers are much shorter than atmospheric towers in order to minimize the pressure differential from top to bottom. Generally, the pressure used in vacuum distillation is in the range of 50 to 100 mmHg, although some lubricating oil stocks may require even lower pressure operating conditions .
