Abstract
Based on the assumptions given below, the authors have given methods for testing thermodynamical consistencies of the data on the equilibrium in isobaric ternary vapor-liquid system in which the third component is non-volatile and of constant concentration. First, [‘Fij’] max and [‘Fijk’RT] i=1-ki=0 are calculated by the zeroth approximation. Secondly, the ternary mixing enthalpy is obtained by Scatchard's method as shown by Eq.(14). Lastly, ΙΔHijΙmax/ΙFij'Ιmax are determined by Herington's relation as given by Eq.(12). The final relations in terms of excess free energies and activity coefficients are given as follows:
For the above relations the authors have given the following conclusions with respect to thermodynamical consistencies of vapor-liquid equilibrium data.
In several ternary systems which are shown by Table 4-Table 7, the final conclusions can be given by Table 10.
