Abstract

The kinetics of heat release in thermal decomposition of guanidinium and ammonium nitrates and their mixtures in the liquid phase in a calorimeter was studied. The kinetic equations of these processes and temperature dependences of the kinetic constants in these equations were evaluated. The oxidation rate constants of guanidinium and ammonium cations with molecular nitric acid in aqueous nitric acid solutions were found; these constants were calculated by solution of the reverse problem for salt melts. The temperatures and ΔH values of melting of the initial salts and their eutectic mixture were determined.
