    Vapor-Liquid and Chemical Equilibria in the Ethanol + Acetic Acid System at 348.15 K.

  • Original language description

    Phase and chemical equilibria in the quaternary water + ethanol + acetic acid + ethyl acetate system was measured in a modified Dvorak and Boublík still. In total, 39 experimental points at 348.15 K were determined. The experimental data were correlatedby means of the maximum likelihood procedure by using the NRTL model. Binary model parameters for the four non-reacting binary subsystems were obtained from available experimental vapor?liquid equilibrium data by using either the Hayden?O'Connell or Marek?Standart correction to account for the nonideality of vapor phase. NRTL parameters for the water + ethyl acetate and ethanol + acetic acid systems were estimated from the global optimization based on the quaternary data. The results obtained from the correlation show a good agreement of calculated and experimental data. The three?dimensional phase diagrams for the quaternary system have been constructed and with use of transformed compositions.

    Chemická a fázová rovnováha v soustavě ethanol+kyselina octová při 248.15 K.

  • Czech description

    Fázová a chemická rovnováha v kvetrnární soustavě ethanol+ethanol+kyselina octová+ethylacetát byla studována v cirkulační aparatuře. Bylo změřeno 39 bodů při 348.15 K. Data byla korelována pomocí NRTL modelu metodou maximální věrohodnosti. Parametry pronereagující binární subsystémy byly použity pro globální optimalizaci kvaternárních dat. Výsledky predikce jsou v dobré shodě s experimentálními daty. Třírozměrné fázové diagramy byly zkonstruovány pomocí transformovaných údajů o složení.
