Total Pressure Measurements for Copper(II) Chloride Plus Methanol Plus Ethanol at 303.15 K
Total pressure is reported as a function of liquid-phase composition for copper(II) chloride + methanol + ethanol at 303.15 K. Pressure was measured as a function of salt concentration along various lines of essentially constant methanol mole fraction (on a salt-free basis). The data were reduced by Barker’s method using an empirical expression for the excess Gibbs free energy of the Liquid phase. Calculated vapor-phase compositions for the two alcohols indicate that the vapor-phase mole fraction of ethanol is increased (ethanol is salted out) by addition of copper(II) chloride to liquid mixtures of methanol and ethanol.
