Abstract
Data have been assembled from the published literature on the enthalpies of solvation for 159 compounds dissolved in N,N-dimethylformamide and for 84 compounds dissolved in tert-butanol. It is shown that an Abraham solvation equation can be used to correlate the experimental enthalpies of solvation in N,N-dimethylformamide and tert-butanol to within standard deviations of 3.08Â kJ/mol and 2.48Â kJ/mol, respectively. The derived correlations provide very accurate mathematical descriptions of the measured enthalpy of solvation data at 298Â K, which in the case of N,N-dimethylformamide span a range of about 108Â kJ/mol. Mathematical correlations have also been derived for predicting the enthalpies of solvation in both solvents based on the Goss modified version of the Abraham model. Expressions based on this latter model were found to correlate the experimental enthalpies of solvation to within an overall average standard deviation of 2.82Â kJ/mol for the two solvents studied.
