Liquid–liquid equilibria of aqueous two-phase systems Containing Polyethylene glycol and Di-sodium hydrogen citrate:Experiment and correlation

Liquid–liquid equilibrium (LLE) data for aqueous Polyethylene glycol 2000 (PEG2000) + Na2C6H6O7 + H2O have been determined experimentally at T = (298.15, 308.15 and 318.15) K. The Nemati equation was used to correlate the binodal data and the coefficients were estimated for the respective temperatures. Furthermore, the Othmer-Tobias and Bancraft, Setschenow equations were used to fit the tie-line data of this system and the parameters are also reported
