摘要：Isobaric vapor-liquid equilibrium (VLE) data for the binary system of isoamyl DL-lactate and isoamyl alcohol were measured at 25.0, 50.0, and 101.3 kPa in a modified Rose equilibrium still. The mixtures do not represent azeotropes. The determined experimental data were checked by Wisniak and van Ness tests to verify their thermodynamic consistency. Meanwhile, the Wilson, NRTL, and UNIQUAC models are adopted to correlate the VLE data, and the parameters of the three models were regressed. The UNIQUAC model showed the best fit to the experimental values relative to the Wilson and NRTL models, and it had the lowest root-mean-square deviations of equilibrium temperature (T) and mole fraction of the vapor phase (y(1)), with the value of 1.54 K and 0.0234, respectively.
