Quaternary Liquid-Liquid Equilibrium of n-Heptane-Toluene-o-Xylene-Propylene Carbonate

Quaternary Liquid-Liquid Equilibrium of n-Heptane-Toluene-o-Xylene-Propylene Carbonate

Liquid-liquid equilibrium data for the system n-heptane/toluene/o-xylene/propylene carbonate were obtained at 25 OC. Experimental tie line data were measured by gas chromatographic analysis. The UNIQUAC and NRTL models were used to predict the quaternary data from the corresponding ternary data. Agr...

Beschreibung
Zusammenfassung:Liquid-liquid equilibrium data for the system n-heptane/toluene/o-xylene/propylene carbonate were obtained at 25 OC. Experimental tie line data were measured by gas chromatographic analysis. The UNIQUAC and NRTL models were used to predict the quaternary data from the corresponding ternary data. Agreement between the predictions and the experimental data was satisfactory.
