摘要：

In the present research, the equilibrium data of two ternary systems, carbon dioxide-toluene-naphthalene and carbon dioxide-ethanol-acridine are determined between 298.15 K and 318.151(and pressure up to 8.9 MPa using a high pressure apparatus. In each experiment, the equilibrium solubilities of naphthalene in toluene and acridine in ethanol decrease by increasing the pressure due to adding the carbon dioxide as the anti-solvent to the liquid phases. Also, the obtained experimental data was correlated by Peng-Robinson and Soave-Redlich-Kwong equation of states along with Van der Waals and Vidal mixing rules. The adjustable parameters of mentioned models are obtained using the experimental data and reported along with average absolute relative deviation of each model. The results show that SRK equation of state with Huron-Vidal mixing rule has the minimum deviation from the experimental data between the studied models for both ternary systems.
