EXCESS-ENTHALPIES OF SOME TERNARY LIQUID-MIXTURES

The excess enthalpies of four ternary liquid mixtures of benzene, toluene, chlorobenzene and 1,4-dioxane with cyclohexane in chloroform have been calculated from the internal pressure data. For the first time the Flory's theory has been used to determine the enthalpies of ternary liquid mixtures. On comparison a good agreement is found in all the mixtures. The calculated excess internal pressure and enthalpy have been used to discuss the results in terms of intermolecular interactions between the components of ternary liquid mixtures.
