(Liquid plus liquid) equilibrium of (NaClO4 + PEG 4000+H2O) ternary system at different temperatures
Phase diagram and (liquid + liquid) equilibrium (LLE) results for {NaClO4 + polyethylene glycol 4000 (PEG 4000) + H2O} have been determined experimentally at T - (288.15, 298.15, and 308.15) K. The Chen-NRTL. modified Wilson and UNIQUAC models were used to correlate the values for the experimental tie-lines. The results show that the quality of fitting is better with the modified Wilson model. (C) 2009 Elsevier Ltd. All rights reserved.
