Abstract
Isothermal vapor-liquid equilibrium data for the system ethanol + 2-propano l + barium iodide at three constant salt molalities (0.5, 1.0 and 1.5 mol(. )kg(-1)) have been measured with the help of headspace gas chromatography a t 40.3, 55.3, and 70.6 degreesC. The experimental data were correlated usin g four electrolyte models: an electrolyte NRTL model, an extended UNIQUAC m odel, an electrolyte UNIFAC model, and the LIQUAC model.
