Development of Abraham model correlations for solute transfer into 2-ethyl-1-hexanol from both water and the gas phase based on measured solubility ratios

Abstract

Experimental solubilities have been determined by spectrophotometric methods for 1-chloro-4-bromobenzene, 1,4-dibromobenzene, 1,4-dichloro-2-nitrobenzene, benzoic acid, 4-nitrobenzoic acid, 3,5-dinitrobenzoic acid, 2-methoxybenzoic acid, 4-methoxybenzoic acid, 3-chlorobenzoic acid, 3,5-dinitro-2-methylbenzoic acid, 2-methylbenzoic acid, 3-methylbenzoic acid, 3,4-dichlorobenzoic acid, benzoin, 4-tert-butylbenzoic acid, 4-chlorobenzoic acid, 3,4-dimethoxybenzoic acid, 3,4,5-trimethoxybenzoic acid and o-acetoacetaniside dissolved in 2-ethyl-1-hexanol at 298.15 K. Our experimental measurements, combined with published solubility data retrieved from the published chemical and engineering literature, were used to derive Abraham model correlations for solute transfer into 2-ethyl-1-hexanol from both water and from the gas phase. The derived Abraham model correlations were found to back-calculate the measured experimental values to within ±0.12 log units (or less).
