A salt dissolved in a mixed solvent is capable, through preferential association or other structure‐related effects in the liquid phase, of altering the composition of the equilibrium vapor phase. Hence salt effect on vapor‐liquid equilibrium relationships provides a potential technique of extractive distillation for difficult separations. The literature pertaining to salt effect in vapor‐liquid equilibrium and in extractive distillation over the period 1966‐present is reviewed, and also the remainder of work up to 1966 not covered in the Part I review.
