ABSTRACT:
A process for the separation of a dissolved solid from an aqueous solution containing it, comprising the steps of (a) adding thereto an organic liquid which is a poor solvent for the dissolved solid and which forms an azeotrope with water, (b) subjecting the mixture to azeotropic distillation to separate at least a major portion of the water, (c) cooling the mixture thereby causing substantially complete separation of the dissolved solids, and (d) separating same from the mother liquor.
