In the vacuum process, the azeotrope (or point where distillation ceases to work) moves toward 100 percent as the pressure is lowered. At a pressure below 1/10 atmosphere, the azeotrope disappears, enabling distilling all the way to 100 percent alcohol. ...

The working principle of molecular distillation

Oct 19, 2021 A distiller based on this principle is called a short-path distiller. The short path distiller (molecular distillation) has a built-in condenser on the opposite side of the heating surface and reduces the operating pressure to 0.001 mbar. The short path distiller is a thermal separation process that works at a pressure of 1 to 0.001 mbar.
