The vapor-liquid equilibrium relations of ethanol-water-calcium chloride and methanol-ethanol-calcium chloride systems have been measured by use of a flow-type apparatus at 25°C. The partial pressure data are reported at salt concentrations of 0, 5, 10, and 15% in mass.
The present vapor-liquid equilibrium data were correlated by an empirical model recently proposed by Hála. It is found that the salting-out and salting-in effects on ethanol-water and methanol-ethanol mixtures by calcium chloride can be illustrated by adjusting the empirical parameter contained in the electrostatic contribution term.
