ABSTRACT
The liquid liquid equilibrium of 1-propanol, 2-propanol, 2-methyl-2-propanol, or 2-butanol + diammonium hydrogen citrate aqueous biphasic systems was studied at 298.15 K. The binodal curves of investigated systems at (298.15 and 308.15) K were measured; the dielectric constant and densities were used to modify the empirical Merchuk equation, and the obtained equation was used for the correlation of all measured binodal data simultaneously. The temperature effect on the studied systems in the (293.15 to 323.15) K temperature range was discussed using the measured cloud-point data at constant salt-to-water mole fraction ratios. Additionally, tie-line compositions are reported at 298.15 K, and the electrolyte nonrandom two-liquid (NRTL) model was satisfactorily used for the correlation of these data; the restricted binary interaction parameters were also obtained. An acceptable agreement between the calculated and the experimental tie-line data was obtained.
