In the vacuum apparatus here, it distills off into the connected receiver flask on the left at only 70 °C. Vacuum distillation or distillation under reduced pressure is a type of distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy.

Vacuum distillation. A Perkin triangle is a specialized apparatus for the distillation of air-sensitive materials. It is named after William Henry Perkin Jr., whose design was approximately triangular. [citation needed] The diagram shows a more modern version, in which the glass taps have been replaced with more air-tight Teflon taps.
Condenser (laboratory) A distillation setup using a Liebig-type condenser (the tilted double-walled tube at the center). A liquid (not visible) in the flask at left is heated by the blue mantle to the boiling point. The vapor is then cooled as it goes through the inner tube of the condenser. There it becomes liquid again, and drips into the ...
Molecular distillation is vacuum distillation below the pressure of 0.01 torr. 0.01 torr is one order of magnitude above high vacuum, where fluids are in the free molecular flow regime, i.e., the mean free path of molecules is comparable to the size of the equipment. The gaseous phase no longer exerts significant pressure on the substance to be ...
