What is Molecular Distillation Process? Molecular distillation is an efficient liquid-liquid separation method, which is to separate substances through the difference among molecular motion mean free path of different substances. Therefore, the whole working process of molecular distillation is about molecular motion. The working process of molecular distillation is as follows: The molecules diffuse from …
As a common evaporator in laboratory and industry, a rotary evaporator has been widely recognized for its excellent distillation and extraction performance. Generally, it is used to remove a volatile solvent from a liquid mixture. A rotary evaporator is mainly composed of following parts: a vacuum pump, a chiller, a condenser pump, a rotating flask …
Molecular distillation system is more complicated than the simple and traditional distillation, which are to separate substances though their different boiling points. It is depending on the different molecular motion mean free path among different substances. In this case, the average free path of steam molecules is greater than the distance between the evaporation surface …
