Estimation of thermodynamic properties of multicomponent systems on the basis of generalized hole theory

In the present work a generalized hole theory is applied to compute the energy of vaporization, heat of vaporization, cohesive energy density, solubility parameter and van der Waals constant of four ternary [viz., cyclohexane + n-heptane + n-hexane (I), toluene + n-heptane + n-hexane (II), n-hexane + n-heptane + n-decane (III), n-hexane + cyclohexane + benzene (IV)] and four quaternary [n-decane + n-hexane + cyclohexane + benzene (VIII), pentane + hexane + cyclohexane + benzene (V), pentane + hexane + benzene + toluene (VI), pentane + cyclohexane + heptane + toluene (VII)] liquid systems at 298.15 K. The calculated values are compared with those obtained experimentally. The present study encourages the concept of the existence of holes in mixtures.
