What is the Difference Between Molecular Distillation and Short Path Distillation ...

Dec 16, 2021 The key difference between molecular distillation and short path distillation is that molecular distillation uses extremely low vacuum pressure and it is a type of short path distillation technique, whereas short path distillation is an analytical technique and a type of distillation that allows the sample to travel a short distance at reduced pressure.

Distillation Distillation is a commonly used method for purifying liquids and separating mixtures of liquids into their individual components. Familiar examples include the distillation of crude fermentation broths into alcoholic spirits such as gin and vodka, and the fractionation of crude oil into useful products such as gasoline and heating oil.

Short Path Molecular Distillation

Short Path Molecular Distillation

Experiments show that on a broad range of molecular weight materials, a relationship exists between the molecular weight and the distillation temperature of the material. There is no predictable temperature at which distillation will occur; condensation begins whenever a sufficient temperature differential occurs between evaporator and condenser.

Molecular distillation occurs at low temperatures and reduces the problem of thermal decomposition. High vacuum also eliminates oxidation that might occur in the presence of air. The rate of evaporation is controlled by the rate at which the molecules escape from the free surface of the liquid and condense on the condenser.
