摘要：

Binodal curves of 1-(2-methoxyethyl)-3-methylimidazolium bromide + potassium carbonate, potassium phosphate, dipotassium phosphate + water aqueous two-phase systems were determined experimentally at T = 288.15, 298.15 and 308.15 K, respectively. Effect of temperature on binodal curves was studied. Two empirical equations were used for reproducing the experimental binodal data. Effective excluded volume (EEV) theory was used to investigate the phase-forming strength of salts PO43->HPO42->CO32-. Additionally, the tie-line data were correlated by the Othmer-Tobias. Bancroft and Setschenow-type equations. (C) 2013 Elsevier B.V. All rights reserved.
