“…However, at high temperatures, the errors become larger. These results have been seen in the other works (Coimbra et al, 2005;Huang et al, 2005;Khimeche et al, 2007). Figures 4 and 5 show Figure 5.…”

Solubility data of organophosphorous metal extractants in supercritical fluids (SCF) are crucial for designing metal extraction processes. We have developed a new equation of state (EOS) based on virial equation including an untypical parameter as BP/RT, reduced temperature and pressure for prediction of solute solubility in supercritical carbon dioxide (SC CO 2 ). Solubility experimental data (solubility of tributylphosphate in SC CO 2 ) were correlated with the two cubic equations of state (EOS) models, namely the Peng-Robinson EOS (PR-EOS) and the Soave-Redlich-Kwong EOS (SRK-EOS), together with two adjustable parameter van der Waals mixing and combining rules and our proposed EOS. The AARD of our EOS is significantly lower than that obtained from the other EOS models. The proposed EOS presented more accurate correlation for solubility data in SC CO 2 . It can be employed to speed up the process of SCF applications in industry.Les données de solubilité d'extractants de métaux organo-phosphorés dans des fluides supercritiques (FSC) sont cruciales pour concevoir des processus d'extraction des métaux. Nous avons développé une nouvelleéquation d'état (ÉÉ) basée sur uneéquation d'état du viriel comprenant un paramètre atypique tel que la température et la pression réduite pour la prédiction de la solubilité du soluté dans du dioxyde de carbone supercritique. Les données expérimentales de solubilité (solubilité du phosphate de tributyle dans CO 2 SC) ontété corrélées avec les deux modèles d'équations d'état cubiques, soit l'ÉÉ Peng-Robinson (ÉÉ-PR) et l'ÉÉ Soave-Redlich-Kwong (ÉÉ-SRK), avec deux paramètres ajustables, les règles de mélange et de combinaison van der Waals et notreÉÉ proposée. L'AARD de notreÉÉ est significativement plus faible que celui obtenuà partir des autres modèles d'ÉÉ. L'ÉÉ proposée présentait une corrélation plus exacte pour les données de solubilité dans le CO 2 SC. Elle peutêtre employée pour accélérer les processus des applications de FSC dans l'industrie.

“…Vatanara et al (2005) reported that beclomethasone dipropionate and budesonide had the same cross-over region at 24.3 MPa. Khimeche et al (2007) observed that the solubility cross-over pressures for 4,4-diaminodiphenylmethane (DADPM) and 1,5-naphtalediamine (1,5 NDA) were around 15.2 and 14.5 MPa respectively. The solubility cross-over region observed in the VCO-SC-CO 2 system in this study tends to be slightly higher than those reported for studies involving other compounds.…”

“…The model adopted by Chrastil relates the solubility of the solute to the density of the supercritical solvent based upon the assumption that one molecule of a solute, A, associates with k molecules of solvent, B, to form a solvate-complex AB k , in an equilibrium state [28,44,45].…”
