Application progress on molecular distillation in isolation and purification for crude substance

Molecular distillation is a new isolation technique.Owing to the characteristic of high vacuum degree,low distillation temperature and short time being hot,this technique can wonderfully ensure the natrural quality of the substance and is widely used in the distillation,condensation and isolation of crude substance.Recent application progress of molecular distillation on isolation and purification in crude subatance was reviewed briefly in this paper.
