Which types of molecular distillation equipment can be divided …

11/5/2018· Now,let''s introduce the molecular distillation equipment. Molecular distillation, is also known as short path distillation.It is a relatively new liquid-liquid separation technology that is not yet widely used in industrial production.It can solve the problems that a large nuer of conventional distillation technologies cannot solve.

Why is molecular distillation also called short path distillation?

Answer (1 of 3): Israr, I believe what you are calling molecular distillation is a process of high vacuum distillation of materials not requiring careful separation of closely-related materials, but typically require separation of the desired material from markedly different
