ABSTRACT
Isothermal vapor-liquid equilibrium data for the system 1,4-dioxane + water + tetrabutylammonium nitrate at 11 constant salt molalities ((0.1, 0.25, 0.50, 0.75, 1.00, 1.50, 2.00, 2.50, 3.00, 3.50, and 4.00) mol?kg-1) have been measured with the help of gas chromatography at (288, 298, and 308) K. Isothermal vapor-liquid equilibrium data for the system acetonitrile + water + tetrabutylammonium bromide at 5 constant salt molalities ((0.20, 0.40, 0.60, 0.80, and 1.00) mol?kg-1) have also been measured with the help of gas chromatography at (298 and 323) K. The experimental data for these systems were correlated using the electrolyte nonrandom two-liquid model.
