The solubility of Acridine in supercritical carbon dioxide was measured at temperatures 313, 323 and 333 K and in the pressure range of 120 to 350 bar using static method. The crossover pressure of Acridine was observed at about 150 bar. The experimental data were correlated using Peng- Robinson (PR) and Soave- Redlich- Kwong (SRK) equations of state (EOS) and van der Waals mixing rule. The binary interaction parameters of the models were reported. The results of average absolute relative deviations (AARD) illustrated good accuracy of the studied models. The results also showed that, among the studied models, PR- vdW 2 model has the minimum AARD (5.08 %).
