Experimental and correlated liquid-liquid equilibrium data for water+1,6-hexanediol+1-pentanol/3-methyl-1-butanol/2-methyl-2-butanol at different temperatures
Liquid liquid equilibria (LLE) data for ternary systems of water + 1,6-hexanediol + 1-pentanol/ 3-methyl-1-butanol/ 2-methyl-2-butanol were measured at (293.15, 303.15, 313.15 and 323.15) K under 101.3 kappa Pa. Cloud-point method was applied to determine the solubility curves data. Distribution coefficient and separation factors for 1,6-hexanediol were calculated from the measured tie-line data to evaluate the extraction effect of alcohols on 1,6-hexanediol. The reliability of experimental LLE data were tested by Othmer-Tobias equation and Hand equation, NRTL and UNIQUAC models were applied to correlate the measured data and the calculated results show that both models can fit the experimental data very well.
