Development of Abraham model correlations for describing solute transfer into 2-methyl-1-butanol from both water and the gas phase from experimental solubility data of crystalline organic compounds

ABSTRACT

Experimental solubilities have been measured at 298.15 K for benzil, biphenyl, pyrene, fluoranthene, acenaphthene, xanthene, fluorene, 1,2,4,5-tetramethylbenzene, 4-tert-butylbenzoic acid, benzoic acid, 4-chloro-3-nitrobenzoic acid, 4-methoxybenzoic acid, 3,4,5-trimethoxybenzoic acid, 3-methyl-4-nitrobenzoic acid, 4-aminobenzoic acid, diphenyl sulphone, 2-ethylanthraquinone, thioxanthen-9-one, thianthrene, o-acetoacetanisidide, sorbic acid, 1,4-dichloro-2-nitrobenzene, 1,4-dibromobenzene, salicylamide, benzoin and trans-stilbene. Results of experimental measurements were combined with published solubility data taken from the published literature to derive Abraham model correlations for transfer of solutes into 2-methyl-1-butanol. The reported Abraham model correlations describe the observed solute transfer coefficients to within an overall average standard deviation of approximately 0.08 log units.
