Molecular Distillation is a special liquid-liquid separation technology, which is different from traditional distillation on the difference boiling point. This is a kind of distillation in high vacuum environment, for the difference of material molecular movement free path, was carried out in the heat sensitive material or high boiling point material distillation and purification process. It is mainly used in chemical, spices, pharmaceutical, petrochemical, plastics, oil and other fields. Know more!
It is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for example vitamins and polyunsaturated fatty acids. This process is characterized by short term exposure of the distillate liquid to high temperatures in high vacuum (around 10^-4 mmHg) in the distillation column and a small distance between the evaporator and the condenser around 2 cm.
In molecular distillation, fluids are in the free molecular flow regime, i.e. the mean free path of molecules is comparable to the size of the equipment.
