Abstract
The enthalpies of dissolution for 5,5′-Bistetrazole-1, 1′-dihydroxy ((H2O)2BTO) and disodium 5,5′-Bistetrazole-1,1′-diolate ([Na2(H2O)4]BTO) in dimethyl sulfoxide (DMSO) at 298.15 K were studied by using a C-80 Calvet microcalorimeter. 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 deduced by the experimental results of the dissolution processes of (H2O)2BTO and [Na2(H2O)4]BTO in DMSO. Finally, the corresponding kinetic equations describing the dissolution processes were dα/dt = 10−2.60(1−α)0.61 for the dissolution of (H2O)2BTO in DMSO, and dα/dt = 10−2.69(1−α)0.62 for the dissolution of [Na2(H2O)4]BTO in DMSO.
