The purification of chemicals has always been an essential part of laboratory and industrial production. As a reliable and efficient purification technology, molecular distillation is widely used in many fields. So what is molecular distillation? What is its principle?

Molecular distillation refers to the distillation of lower boiling point substances in the mixture under controlled pressure to achieve the purpose of fine purity. It mainly uses the physical and chemical characteristics of different boiling points of different substances to separate. At the same time, molecular distillation also need to control the flow, temperature and pressure and other factors, in order to achieve efficient separation.

In particular, the principle of molecular distillation is to output the low-boiling components of the mixture while retaining the high-boiling components. In actual production, molecular distillation usually adopts multi-stage operation. After each stage of distillation, the target compound can be separated more cleanly, which is also the key to improve the effect of molecular distillation.

In molecular distillation, it is also important to control the temperature and pressure. As the liquid heats up, the boiling point rises and the evaporation rate increases. However, forced heating of the liquid will destroy the level in the internal pattern of the molecule, which will lead to fragmentation and degradation, so that the compound loses its original properties. Therefore, it is necessary to ensure that the compound can be saturated evaporated in the flowing state by means of slow heating and temperature gradient control. The advantages of

molecular distillation technology are also obvious. First of all, it can separate most of the mixture of simple compounds in the process. At the same time, molecular distillation can also purify compounds quickly and efficiently, avoiding many common difficulties of traditional chemical methods. In addition, molecular distillation technology can also be widely used for the production and purification of toxic or volatile compounds.

molecular distillation is not only an efficient and fast chemical purification technology, but also an essential tool to improve the quality and efficiency of our chemical treatment. Whether you are a laboratory researcher or an industrial production worker, on the basis of mastering the principle of molecular distillation, strengthening the understanding of its application can make molecular distillation play a better effect.
