EXCESS-ENTHALPIES OF SOME TERNARY LIQUID-MIXTURES

The excess enthalpies of four ternary liquid mixtures of benzene, tolu ene, chlorobenzene and 1,4-dioxane with cyclohexane in chloroform have been calculated from the internal pressure data. For the first time t he Flory's theory has been used to determine the enthalpies of ternary liquid mixtures. On comparison a good agreement is found in all the m ixtures. The calculated excess internal pressure and enthalpy have bee n used to discuss the results in terms of intermolecular interactions between the components of ternary liquid mixtures.
