MEASUREMENT OF SALT EFFECT ON VAPOR-LIQUID EQUILIBRIA BY BUBBLE AND CONDENSATION POINT METHOD

Abstract

Based on the bubble and condensation point method, vapor-liquid equilibrium data in salt solutions have been measured at atmospheric pressure for the systems methanolethanol-CaCI₂ and iso-propanol-water-CaCI₂. For the former system, the relative volatility of methanol to ethanol was decreased by the salt effect of GaCI₂. For the latter system, the azeotrope could be eliminated by increasing the concentration of CaCl₂.
