Updated Abraham model correlations for describing solute transfer into both 2-Pentanol and 3-Methyl-1-butanol based on much larger data sets

ABSTRACT

Mole fraction solubilities of 4-tert-butylbenzoic acid, 3-chlorobenzoic acid, 2-methyl-3-nitrobenzoic acid, 3-methyl-4-nitrobenzoic acid, 3,4,5-trimethoxybenzoic acid, isophthalic acid, 3-hydroxybenzoic acid, o-acetoacetaniside, 2,4-dihydroxybenzophenone, benzoin, paracetamol, and 1,4-dichloro-2-nitrobenzene in 2-pentanol at 298.15 K. Results of the experimental measurements, combined with published literature data, were used to calculated revised equation coefficients for the Abraham model correlations for the 2-pentanol solvent. Revised equation coefficients are also reported for the 3-methyl-1-butanol Abraham model correlations based on much larger data sets containing 95 experimental data points.
