Distillation
Steam distillation
As we discussed in concept
Steam Distillation -
This method is used to separate substances which are steam volatile and are immiscible with water.
- wherein
e.g. O-nitrophenol and P-nitrophenol
Those substance which is insoluble in water and possesses a vapour pressure of 10-15 mm Hg at 371K can be purified by steam distillation.
