ABSTRACT
The enthalpies of dissolution for ammonium dipicrylamide (ADPA) in dimethyl sulfoxide(DMSO) and N-methl pyrrolidone(NMP) were measured using a RD496-2000 Calvet microcalorimeter at 298.15 K under atmospheric pressure. Empirical formulae for the calculation of the enthalpies of dissolution (AdissH) were obtained from the experimental data of the dissolution processes of ADTA in DMSO and NMP. The linear relationships between the rate (k) and the molality (b) were found. The corresponding kinetic equations describing the two dissolution processes were for the dissolution of ADPA in DMSO, and for the dissolution of ADPA in NMP, respectively.
