Salt effect in vapor‐liquid equilibrium, part II

Previous work in the field of salt effect in vapor‐liquid equilibrium and the theory involved are reviewed briefly. Vapor‐liquid equilibrium data at atmospheric pressure are reported for the systems methanol‐water, ethanol‐water, and n‐propanol‐water, each saturated with a variety of common inorganic salts. A simple equation is proposed for the representation of salt effect. An attempt is made to ascertain the theoretical significance of this equation, and in so doing, to relate salt effect in vapor‐liquid equilibrium to the properties of the system components.
