Effect of Alkaline-earth Chlorides on Vapor-liquid Equilibrium of Acetic-water System

Experimental data concerning the isobaric vapor-liquid equilibrium of the system acetic acid-water saturated with the chlorides of calcium, strontium, and barium at one atmosphere are presented. The results show a considerable effect due to salt addition. Reversal of relative volatilities was observed in all cases. Composition and boiling points of the azeotropes thus formed are reported
