Isobaric vapor-liquid equilibria for water plus acetic acid plus potassium acetate

Isobaric vapor-liquid equilibria for water + acetic acid + potassium acetate at different salt concentrations as well as for solvent + potassium acetate binary mixtures have been obtained at 100 kPa. Potassium acetate is more effective in the salting-out effect (on water) than lithium and sodium acetates. The eNRTL-CT model, which is a combination of electrolyte nonrandom two-liquid and chemical theory models, has been used to fit the experimental data. The binary parameters of the model have been obtained from the experimental binary vapor-liquid equilibria which have been used to suitably reproduce the vaporliquid equilibria (VLE) for water + acetic acid + potassium acetate ternary system.
