[Chemical Knowledge]：Molecular Distillation: The Technology of Screening Liquid Molecules

Read： 435 Time：20months ago Source：Transform the World with Simplicity

As a special distillation technology, molecular distillation can separate various components in liquid mixtures to obtain high purity and high concentration substances. This technology mainly uses the force difference between molecules, through heating and cooling under specific conditions, so that different molecules can be separated. The principle of

molecular distillation is similar to ordinary distillation, using different boiling points to separate substances. However, due to the special fractionation column used in molecular distillation, the column contains many precision manufacturing holes, the diameter of these holes is very small, only nano-scale. When the liquid mixture enters the fractionation column, each molecule will behave differently when passing through the hole because of its own size and the interaction force between other molecules. This different performance is to screen the material, some large molecules screen out, and small molecules through.

In molecular distillation, due to the difference in molecular size and interaction force, the time of molecules in these holes is different, so some molecules will retain the material in the column for a longer time, and impurities will be more quickly excluded. In this way, through the control of heating and cooling, we can reduce the boiling point of different molecules, so that they are gradually volatilized and collected, so as to obtain the target substance. The material thus separated has extremely high purity and concentration, and can be used in food, cosmetics, pharmaceuticals and other fields. It is

worth mentioning that molecular distillation is not only a technique for separating molecules from liquid mixtures, but also can be applied to various gases and solid materials. It can be said that molecular distillation is one of the separation technologies with the widest application range, the highest technical difficulty and the highest research level in the world today.

molecular distillation is a very precise and efficient separation technology, which can separate the substances in the liquid mixture very pure, and has a wide range of applications. With the continuous development and improvement of technology, it is believed that molecular distillation will become a more popular and competitive separation technology.
