Abstract

Using heats of mixing data only, the temperature dependent parameters of the local composition models NRTL and UNIQUAC have been estimated and presented in the first part of this series. Here, these parameters are employed to predict the calorimetric properties: these are the heats of mixing h(E), partial molar heats of mixing at infinite dilution DELTA-H(i) and excess heat capacities C(p)E. Limiting activity coefficients are also estimated at different isotherms. All the predictions have been compared with experimental values.
