Abstract
The molar enthalpies of dissolution for 3,6-bis(1H-1,2,3,4-tetrazol-5-yl-amino)-1,2,4,5-tetrazine (BTATz) were measured in N-methyl-2-pyrrolidone (NMP) and dimethyl sulfoxide (DMSO) using an RD496-2000 Calvet microcalorimeter at 298.15 K under atmospheric pressure. Empirical formulae for the calculation of the molar enthalpies of dissolution (Δdiss H), relative partial molar enthalpies (Δdiss H partial), and relative apparent molar enthalpies (Δdiss H apparent) were obtained from the experimental results of the dissolution processes of BTATz in NMP or DMSO. Furthermore, the corresponding kinetic equations describing the two dissolution processes are dα/dt = 10−3.55(1 − α)0.57 for the dissolution of BTATz in NMP, and dα/dt = 10−3.74(1 − α)0.63 for the dissolution of BTATz in DMSO, respectively.
