Abraham model correlations for enthalpies of solvation of organic solutes dissolved in methyl acetate and octane

Abstract

Data have been assembled from the published literature on the enthalpies of solvation for 63 compounds dissolved in methyl acetate and for 67 compounds dissolved in octane. It is shown that an Abraham solvation equation can successfully correlate the experimental enthalpies of solvation in both methyl acetate and octane to within standard deviations of 2.89 and 2.15 kJ mol−1, respectively. The correlations determined in the present study provide very accurate mathematical descriptions of the measured enthalpy of solvation data at 298 K, which in the case of methyl acetate span a range of about 110 kJ mol−1.
