The excess heat capacities of seven nonassociated systems such as cyclohexane-benzene were determined at 298.15K. latm, using, Calvet microcalorimeter. On the basis of Liebremann model, correlation between excess entropy and excess volume was introduced, the model estimating CEp of nonassoiation binary liquid mixture with pure liquid property and excess volume was established. The excess heat capacities of seven nonassociated systems were calculated by the model, the computation values fit the experiment values on the whole concentration.
