ABSTRACT

The equilibrium of the ternary electrolyte system at 101.3 kPa, water + 1-propanol + ammonium chloride (NH4Cl), has been investigated at 298.15 K and at the boiling temperature to determine the shape of equilibrium surfaces and regions on the phase diagram. The data obtained have been compared with previously published experimental data showing their inconsistency. Moreover, the results obtained allow us to study the shape of the phase diagram of the system, to analyze the evolution with the temperature of this equilibrium diagram and to show the differences with a similar system such as water + NaCl + 1-propanol. Finally, it has been shown that the extended UNIQUAC model for electrolytes predicts the different equilibrium regions and boiling temperatures but there are great discrepancies between experimental and calculated equilibrium concentrations.
