摘要：

Isobaric vapour-liquid and vapour-liquid-liquid equilibrium data for the water + 1-butanol +toluene ternary system were measured at 1013 kPa with a modified VLE 602 Fischer apparatus. In addition, the liquid-liquid equilibrium data at 313.15 K were measured and compared with data from other authors at different temperatures. The system exhibits a ternary heterogeneous azeotrope whose temperature and composition have been determined by interpolation. The thermodynamic consistency of the experimental vapour-liquid and vapour-liquid-liquid data was checked by means of the Wisniak's L-i/W-i consistency test. Moreover, the vapour-liquid and the liquid-liquid equilibrium correlation for the ternary system with NRTL and UNIQUAC models, together with the prediction made with the UNIFAC model, were studied and discussed.
