Abstract
Experimental mole fraction solubilities are reported for acenaphthene, o-acetoacetanisidide, acetylsalicylic acid, anthracene, benzil, benzoic acid, benzoin, 4-tert-butylbenzoic acid, 3-chlorobenzoic acid, 4-chlorobenzoic acid, 2-chloro-5-nitrobenzoic acid, 4-chloro-3-nitrobenzoic acid, 3,4-dichlorobenzoic acid, 3,4-dimethoxybenzoic acid, 3,5-dinitrobenzoic acid, diphenyl sulphone, fluoranthene, 9-fluorenone, 2-hydroxybenzoic acid, 2-methoxybenzoic acid, 4-methoxybenzoic acid, 2-methylbenzoic acid, 3-methylbenzoic acid, 2-methyl-3-nitrobenzoic acid, 3-methyl-4-nitrobenzoic acid, 4-methyl-3-nitrobenzoic acid, 4-nitrobenzoic acid, pyrene, salicylamide, 3,4,5-trimethoxybenzoic acid, and xanthene dissolved in isopropyl acetate at 298.15 K. Results of experimental measurements, combined with published solubility data for an additional 11 organic compounds, were used to derive Abraham model correlations that described the solubilising properties of the isopropyl acetate mono-solvent. The derived Abraham model correlations back-calculate the observed experimental data to within 0.10 log units (or less).
