ABSTRACT

Excess molar enthalpies, HEijk of o-toluidine (i) + tetrahydropyran (j) + pyridine or a- or a- or a- picoline or benzene or toluene (k) ternary mixtures have been measured over entire mole fraction at 308.15K using 2-drop calorimeter. The experimental data have been fitted to Redlich-Kister equation to evaluate ternary parameters along with their standard deviations. The HEijk values for the studied mixtures except those of o-toluidine (i) + tetrahydropyran (j) + toluene (k) are negative over entire composition range. The topology of the constituents of the mixtures has been utilized to (Graph theory) predict HEijk values of the investigated mixtures. The observed HEijk data have also been analyzed in terms of Prigogine-Flory-Patterson theory, It has been observed that values predicted by Graph theory compare well with their corresponding experimental values.
