The test particle method proposed by Widom was applied to calculate the solubilities of naphthalene in supercritical carbon dioxide at 308.15 and 328.15 K. The Lennard-Jones (12-6) potential was used as the intermolecular potential. The solubilities of naphthalene in supercritical carbon dioxide have been calculated quantitatively by introducing two binary interaction parameters k12 and l12 between unlike molecules. The binary interaction parameter K12 is used to calculate the energy parameter ε12, while l12 is used to calculate the size parameter σ12. The calculated results by the Monte Carlo simulation show in good agreement with the experimental data.
