Experimental solubilities are reported for anthracene dissolved in ternary methyl tert-butyl ether + 1-propanol + 2,2,4-trimethylpentane, methyl tert-butyl ether + 2-propanol + 2,2,4-trimethylpentane, methyl tert-butyl ether + 1-butanol + 2,2,4-trimethylpentane, methyl tert-butyl ether + 2-butanol + 2,2,4-trimethylpentane, and methyl tert-butyl ether + 2-methyl-1-propanol + 2,2,4-trimethylpentane solvent mixtures at 25°C and atmospheric pressure. Nineteen compositions were studied for each of the five solvent systems. Results of these measurements are used to test the predictive ability of the ternary solvent form of the combined NIMS/Redlich-Kister equation. Computations showed that the model predicted the observed solubility behavior to within an overall average absolute deviation of about 1.7%, which is comparable to the experimental uncertainty of (1.5%.

Nineteen compositions were studied for each of the five solvent systems. Results of these measurements are used to test the predictive ability of the ternary solvent form of the combined NIMS/Redlich-Kister equation.Computations showed that the model predicted the observed solubility behavior to within an overall average absolute deviation of about 4.0%.

Experimental solubilities are reported at 25.0°C for hexachlorobenzene dissolved in 42 different organic nonelectrolyte solvents containing ether-, chloro-, hydroxy-, ester, methyl-, and tert-butyl-functional groups. Results of these measurements are used to test the applications and limitations of expressions derived from Mobile Order model. For the 33 solvents for which predictions could be made computations show that Mobile Order model does provide fairly reasonable estimates of the saturation mole fraction solubilities. Average absolute deviation between predicted and observed values is 210%. In comparison, the average absolute deviation is 2 060% when ideal solution behavior is assumed.Résumé : Opérant à 25,0°C, on a mesuré les solubilités expérimentales de l'hexachlorobenzène en solution dans quarante-deux solvants organiques non électrolytiques qui comprennent des groupes substituants éther, chloro, hydroxyle, ester, méthyle et tert-butyle. On a utilisé les résultats de ces mesures pour vérifier les applications et les limitations d'expressions dérivées du modèle de l'ordre mobile. Les trente-trois solvants pour lesquels il a été possible de faire des calculs montrent que le modèle de l'ordre mobile conduit à des évaluations assez raisonnables des solubilités en fraction molaire de la saturation. La déviation absolue moyenne entre les valeurs prévues et observées est de 210%. Pour fins de comparaison, la déviation absolue moyenne est de 2 060% lorsqu'on fait l'hypothèse que le comportement de la solution est idéal.Mots clés : solubilités de l'hexachlorobenzène, solvants organiques non électrolytiques, prévisions des solubilités.
