Abstract
Dissolution enthalpies of NaI in mixtures of N,N-dimethylformamide with urea, formamide, acetamide and N,N-dimethylacetamide were measured. The results were compared with data measured earlier for other DMF — non-electrolyte mixtures. The enthalpic pair interaction coefficients,h xy (Na+I− — non-electrolyte) in DMF were calculated and analysed together with the appropriate data concerning other Na+I− — non-electrolyte pairs in DMF. The group interaction coefficients illustrating the interactions of Na+I− with the CH2, OH, O, CO, ‘Pep’ and ‘iPep’ groups were determined and discussed.
