Enthalpic pair interaction coefficients of nal-non-electrolyte mixtures in dmf solution at 25°C: Part 2. application of the group additivity concept to interactions in dmf solutions

Abstract

Dissolution enthalpies of Nal in mixtures of 2-methoxyethanol, ethylene glycol and 1,4-dioxane with N, N-dimethylformamide have been measured. From these data the enthalpic pair interaction coefficients, h xy (Na +I −-non-electrolyte) in DMF have been determined and analysed together with the appropriate data concerning other Na +I −-non-electrolyte pairs in DMF. The Wood-Savage group additivity model appeared to be applicable to correlation of h xy coefficients in DMF solution.
