Molecular distillation is also called short path molecular distillation, which is a distillation method under high vacuum. The average free path of the vapor molecules is greater than the distance between the evaporation surface and the condensation surface, so that the difference in evaporation rate of each component in the liquid can be used. Molecular distillation is to separate the mixtures of liquids.
Molecular distillation has a very high efficiency on the concentration and extraction of substances. Therefore, people always use molecular distillation to extract cannabis, because it can process a big bulk of cannabis at the same time. There are so many popular cannabis products made by molecular distillation in the market.
- The molecular distillation provides the best separation method for high boiling point, heat sensitive and easily oxidized materials. Because the molecular distillation can be operated under a temperature much lower than boiling points of materials and the retention time of materials is short.
- The molecular distillation can effectively remove substances in the liquid, such as organic solvent, odor, etc. It is a very effective method for the liquid desolvation after solvent extraction.
- The molecular distillation can distill out the desired product selectively as well as remove other impurities. More than two components can be separated at the same time by multistage separation.
- The fractional distillation is a physical process, which can protect the separated components well from contamination and damage.

Introduction to Molecular Distillation
Working Principle
Its working principle is to separate substances by the differences in mean free path of molecular motion of different substances. Because the weight of different substances are different, the different substances will run into different ways during the working process. Therefore, that’s why the different substances are separated by molecular distillation.
Pressure Range
Molecular distillation is a liquid-liquid separation method that works under high vacuum. Generally, the pressure range of molecular distillation is under 0.01 torr, which is under 1.3 Pa. This very high vacuum environment makes sample materials can boil at the temperatures that are much lower than sample materials’ boiling points, which saves a lot of energy.
Wide Application
Molecular distillation can distill food and protect the nature at the same time in food-making field;
It can extract essential oil, lanolin and other substances in make-up field;
It can distill Vitamin A and Vitamin E from mixture in pharmaceutical field.
Besides above, there are still more applications of molecular distillation.
CBD Essential Oil
- It is widely used on distilling cbd from hemp. And the cbd extracted from hemp can be used in many different fields.
- Essential oils are made through the extraction and concentration of substances by molecular distillation. Essential oils have high concentration, so making essential oils takes a lot energy for molecular distillation.
