Vapor-liquid equilibrium data have been obtained for the systems methyl acetate-methanol and ethyl acetate-ethanol with potassium acetate and with zinc chloride at atmospheric pressure. The relative volatility increased little for the ethyl acetate-ethanol-potassium acetate system, but it increased considerably for other systems. The breaking of azeotropy was observed in the systems with zinc chloride.
An empirical equation is proposed to correlate vapor-liquid equilibrium data for the systems containing salt. The equation includes terms of both salt concentration and liquid composition.
