Experimental solubilities have been determined for acenaphthene, biphenyl, benzoic acid, 3-nitrobenzoic acid, 4-nitrobenzoic acid, 2-methoxybenzoic acid, 4-methoxybenzoic acid, 3,4-dimethoxybenzoic acid, 4-aminobenzoic acid, 4-chlorobenzoic acid, 3,5-dinitro-2-methylbenzoic acid, 2-methylbenzoic acid, 3-methylbenzoic acid, 4-chloro-3-nitrobenzoic acid, 2-chloro-5-nitrobenzoic acid, 2-hydroxybenzoic acid, acetylsalicylic acid, 3,4-dichlorobenzoic acid, benzil, salicylamide, trans-stilbene, benzoin, and 9-fluorenone dissolved in 2-methoxyethanol at 298 K. Experimental infinite dilution activity coefficients and gas-to-liquid partition coefficients were measured for acetone, methanol, acetonitrile, butyl acetate, pyridine, 2-propanol, and dichloromethane in 2-methoxyethanol based a headspace gas chromatographic method. The measured solubility data, combined with published activity coefficients for several liquid organic solutes and solubility data for hydrogen gas, carbon dioxide, anthracene, pyrene, 2-nitrobenzoic acid, 2-chlorobenzoic acid, 3-chlorobenzoic acid, and 4-nitroaniline were used to derive Abraham model correlations for describing solute transfer into 2-methoxyethanol. The derived Abraham model correlations describe the experimental data to within 0.16 log units (or less).
