    Fractional crystallisation is the method that can be used to separate two compounds with different solubilities in a solvent S. A hot saturated solution of these two compounds is allowed to cool, the less soluble compound crystallises out while the more soluble remains in the solution. The crystals are separated from the mother liquor and the mother liquor is again concentrated and the hot solution again allowed cooling when the crystals of the second compound are obtained. These are again filtered and dried.
