The study of this system started from the importance that acetonitrile has as thecomponent of some mixtures appearing in plastics synthesis or as a consequence of theextractive distillation in some industrial processes. The paper presents a systematic and criticalstudy of the isothermal equilibrium acetonitrile-water system at 20, 30 and 40ºC. The systemspresent a maximum in the total vapour pressure diagram which is moving with temperature. Theprocessing of the experimental data existing in the literature [1-3] on acetonitrile-water system aswell as the authors experimental data obtained under isothermal conditions at 40ºC in aninstallation based on the static principle, p=f(x), were presented. The activity coefficients werecorrelated and generalized on the basis of several models of the liquid state, i.e, by Margules,Wilson, NRTL and UNIFAC equations. The analysis of the correlation shows that the bestgeneralized equation for this system is UNIFAC with a deviation in GE/RT of the order of 10-2and kij=0.01. |
