ABSTRACT
Liquid-liquid equilibrium (LLE) data for the ternary system 1-butanol + 3-methyl-1-butanol + water were measured at T = 298.15, 333.15 and 368.15K under atmospheric pressure, respectively, in this article. The reliability of the experimental data was checked by Othmer-Tobias, Bachman and Hand correlations. Moreover, the NRTL and UNIQUAC activity coefficient models were applied to correlate the measured data and both of them gave a root-mean-square deviation (rmsd) of less than 0.0057. The results showed that both models were suitable for the determination of LLE data of the studied system at the investigated temperatures.
