In total, 63 experimental points at 353.15 K and 16 points at 101.325 kPa were determined. The experimental data were correlated by means of the maximum likelihood procedure by using the NRTL model. Binary model parameters for the four nonreacting binary subsystems were obtained from available experimental vapor-liquid equilibrium data by using either the Hayden-OŽConnell or Marek-Standart correction as appropriate, to account for the nonideality of the vapor phase. NRTL parameters for the water + isopropyl acetate and 2-propanol + acetic acid systems were estimated from the global optimization based on the quaternary data. The results obtained from the correlation show a good agreement with experimental data. Three-dimensional phase diagrams for the quaternary system have been constructed and a possible location of a saddle reactive azeotrope was found.
