Abstract
The Prigogine-Flory theory is applied to isothermal compressibilities, at 25, 35, 45 and 60°C and to heats of mixing at 25°C for cyclohexane + n-alkane systems. To this purpose, the van der Waals and the Lennard-Jones potentials have been adopted. The energy parameter ϰ12 has been calculated from the experimental data, and its dependence on the n-alkane number of carbons has been studied. Taking the ϰ12 value obtained for the equimolecular mixture, the excess functi1/ns (∂VE/∂P)T, HE and VE have been calculated and the results compared with experimental values.
