Molecular distillation, also known as short-path distillation, is a specialized liquid-liquid separation technique that utilizes the differences in the average free path of the movement of molecules of different substances to achieve separation under high vacuum conditions.

  Unlike traditional distillation, which relies on the “boiling point difference” for separation, molecular distillation primarily depends on the “average molecular free path difference.” Therefore, it is particularly suited for the separation and purification of substances with high boiling points, sensitivity to heat, and susceptibility to oxidation. It is hailed as the “most advanced distillation technology in the world.”

  Molecular distillation is the crown jewel of modern separation technology. It has overcome the temperature limitations of traditional distillation, providing an ideal solution for the purification of high-value, heat-sensitive materials. It is an indispensable key process in the fields of biotechnology, high-end food, and fine chemicals.
