Tóm tắt

The Savage and Wood group additivity method has been applied to enthalpic pair interaction coefficients of more than 30 solutes dissolved in N,N-dimethylformamide. The results are not satisfactory. Better results are obtained by using a method which accounts for the differences in the numbers of molecular groups between solute and solvent molecules. With this excess group additivity method reasonable correlations are obtained even for solutes as large as dipeptide amides.
