Ternary Parameters

The liquid-liquid equilibrium was measured at 20 °C in the title quaternary system and in the three nitromethane-containing ternary subsystems. The data were compared with those predicted by a superposition of the Wilson and Redlich-Kister equations including the ternary parameters. The agreement between the observed and calculated data is very good both for the quaternary system and for the three ternary systems.

Good Agreement

Liquid-liquid equilibria were measured at 20 °C in the W-MeOH-MTBE-EG quaternary system (W is water, MeOH is methyl alcohol, MTBE is methyl tert-butyl ether, and EG is ethylene glycol) and in the W-MeOH-MTBE, W-MTBE-EG and MeOH-MTBE-EG ternary systems. In the W-MeOH-MTBE-EG, W-MeOH-MTBE, and MeOH-MTBE-EG systems, the vapour-liquid equilibria at atmospheric pressure were also measured. The experimental data of the quaternary system were compared with those modelled by superposition of the Wilson and Redlich-Kister equations with the ternary term, whose parameters were determined based on the corresponding binary and, in some cases, ternary systems. A very good agreement was obtained for both the liquid-liquid and vapour-liquid equilibria.

Calorimetric Measurements

Calorimetric measurements of excess enthalpies are reported for the three ternary systems (1-propanol + methyl tert-butyl ether + (n-hexane, or 2,3-dimethylbutane, or cyclohexane)) at 298.15 K. Smoothing equations, fitted to the results, were used to construct constant enthalpy contours on a Roozeboom diagram for each of the systems.
