Insternal pressure and excess enthalpy of liquid mixtures

Abstract

Based on the general mixing model of liquids suggested by our previous work, the reasonable modifications are performed for some approximate assumptions and mixing rules. A relationship between the excess enthalpy of liquid mixture and the internal pressure of components is obtained, which has two adjustable correct coefficients for normal liquid mixtures and three for alcohol-hydrocarbon mixtures. The calculated results for sixteen binary liquid mixtures show that the relationship not only can describe the variation of excess enthalpy with the concentration for ordinary liquid mixtures, but also can apply to the complex systems which have S-shaped curves in the H^E-x diagram.
