In this work, the phase behavior of mixed solvent electrolyte systems containing 1-butanol + water + ammonium chloride at temperatures of 298.15, 308.15 and 318.15 K and at atmospheric pressure have been studied experimentally and theoretically. For the studied systems, liquid-liquid equilibrium has been observed throughout the studied temperature range. Ammonium chloride shows a salting out effect in the two phase region, while temperature has a minor effect on the liquid-liquid equilibria in the studied temperature range. The measured experimental data have been modeled using a modified version of the extended UNIQUAC model. The model has been found to give a satisfactory description of LLE data obtained in this work, with an average absolute deviation of less than 1.5% in calculated mass fractions compared to experimental data.
