Popis: Vapour-liquid equilibrium (VLE) data are reported for five binary systems involving aromatic hydrocarbons (toluene, ethylbenzene, o-xylene, m-xylene, and p-xylene) and tripropylene glycol (2-[2-(2-hydroxypropoxy)propoxy]propan-1-ol). VLE data was determined by using a static method for the binary mixtures at temperatures within 305.15 K–496.15 K. The p-T-x experimental data obtained were correlated using the NRTL model, in order to obtain the binary interaction parameters for each mixture. We compared the T-x-y diagrams determined based on the NRTL resulted parameters with the diagrams calculated using the UNIFAC predictive model and IDEAL model. We observed differences between the T-x curves calculated with the NRTL model that includes the binary interaction parameters resulting from the experimental VLE data and the T-x curves calculated with UNIFAC predictive model and IDEAL model.
