Calorimetric measurements of the heat of mixing have been made at 25 �C and 40 �C for binary mixtures of triethylamine with methanol, and at 25 �C and 45 �C for binary mixtures of triethylamine with ethanol, n-propanol, and n-butanol. It is found that the heat of mixing for these systems becomes slightly less negative as the temperature is increased. However, apart from methanol, the size of the alcohol molecule has little effect on the heat of mixing. The results obtained are compared with those calculated from vapour pressure data in an earlier paper.

The Wilson, the enthalpic Wilson and the Orye equations were used for the simultaneous correlation of extensive data sets on VLE and heats of mixing of eight binary systems hydrocarbon-n-alcohol, viz. benzene-methanol, -ethanol, -n-propanol, -n-butanol, cyclohexane-ethanol, -n-propanol, -n-butanol and n-heptane-ethanol. The expected quadratic temperature dependence of parameters of these equations makes a good simultaneous description possible of excess free enthalpy and heat of mixing as a function of temperature. The Wilson equation gives demonstrably the best description of the experimental data. All the equations were as well used to predict excess heat capacities for the systems listed and the confidence intervals were estimated for the predicted results. The comparison with experimental data for four of these systems shows that the predicted excess heat capacities are in general in good agreement with the experiment; however, the Wilson equation yielded again the best results.
