Abraham model correlations for enthalpies of solvation of organic solutes dissolved in N,N-Dimethylacetamide, 2-butanone and tetrahydrofuran (UPDATED) at 298.15 K

ABSTRACT

Published experimental enthalpy of solution data and excess molar enthalpy of mixing data have been compiled from the chemical and engineering literature for systems containing N,N-dimethylacetamide, 2-butanone and tetrahydrofuran. The compiled experimental data are used to calculate enthalpies of solvation of organic solutes and inorganic gases dissolved in the three forementioned organic solvents. Abraham model correlations are derived from the calculated enthalpies of solvation. The derived Abraham model expressions back-calculate the experimental solvation enthalpies in N,N-dimethylacetamide, 2-butanone and tetrahydrofuran to within standard deviations of 3.6, 2.2 and 3.4 kJ/mole, respectively.
