DESCRIPTION. Molecular distillation is a distillation method that operates in a high vacuum. At this time, the average free path of the vapor molecule is greater than the distance between the evaporation surface and the condensing surface, so that the difference in the evaporation rate of each group in the material liquid can be used to separate the liquid mixture.
