Abstract
Vapor-liquid equilibrium data was determined by using a static method for the binary mixtures of dipropylene glycol (4-oxa-2,6-heptanediol) with benzene, toluene, ethyl benzene. o-xylene, m-xylene, and p-xylene at temperatures within 293.15 K-481.15 K. The p-T-x experimental data obtained was regressed with NRTL and UNIQUAC thermodynamic models in order to obtain the binary interaction parameters of the models, specific to each mixture. Furthermore, the T-x-y diagrams were determined based on these parameters and then compared with the diagrams calculated using the UNIFAC predictive model. We observed differences between the T-x curves calculated with the two models mentioned above and the UNIFAC predictive model. (C) 2014 Elsevier B.V. All rights reserved.
