Evaluation of decomposition kinetics of energetic materials in the combustion wave / V. P. Sinditskii, V. Y. Egorshev, V. V. Serushkin et al. // Thermochimica Acta. — 2009. — Vol. 496, no. 1-2. — P. 1–12. Experimental data on burning rates and surface temperatures have been shown to allow deriving unique information on decomposition kinetics of energetic materials at high temperatures, provided combustion of these materials occurs in the condensed phase. In the paper, kinetic parameters of the leading reaction on combustion of four solid rocket propellant oxidizers: ammonium perchlorate (AP), ammonium nitrate (AN), ammonium dinitramide (ADN), and hydrazine nitroformate (HNF), as well as six energetic fillers: 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX), 1,3,5-trinitro-1,3,5-triazacyclohexane (RDX), bicyclo-1,3,5,7-tetranitro-l,3,5,7-tetraazacyclooctane (bicyclo-HMX), hexanitrohexaazaisowurtzitane (CL-20), 3,3'-diamino-4,4'-azofurazan (DAAzF), and 3-nitro-l,2,4-triazole-5-one (NTO) are evaluated from available combustion data.

Thermal decomposition of nto: an explanation of the high activation energy // Propellants, Explosives, Pyrotechnics. — 2007. — Vol. 32, no. 4. — P. 277–287. Burning rate characteristics of the low-sensitivity explosive 5-nitro-1,2,4-triazol-3-one (NTO) have been investigated in the pressure interval of 0.1–40 MPa. The temperature distribution in the combustion wave of NTO has been measured at pressures of 0.4–2.1 MPa. Based on burning rate and thermocouple measurements, rate constants of NTO decomposition in the molten layer at 370–425 oC have been derived from a condensed-phase combustion model (k=8.08⋅1013⋅exp(−19420/T) s−1. NTO vapor pressure above the liquid (ln P=−9914.4/T+14.82) and solid phases (ln P=−12984.4/T+20.48) has been calculated. Decomposition rates of NTO at low temperatures have been defined more exactly and it has been shown that in the interval of 180–230 oC the decomposition of solid NTO is described by the following expression: k=2.9⋅1012⋅exp(−20680/T). Taking into account the vapor pressure data obtained, the decomposition of NTO in the gas phase at 240–250 oC has been studied. Decomposition rate constants in the gaseous phase have been found to be comparable with rate constants in the solid state. Therefore, a partial decomposition in the gas cannot substantially increase the total rate. High values of the activation energy for solid-state decomposition of NTO are not likely to be connected with a sub-melting effect, because decomposition occurs at temperatures well below the melting point. It has been suggested that the abnormally high activation energy in the interval of 230–270 oC is a consequence of peculiarities of the NTO transitional process rather than strong bonds in the molecule. In this area, the NTO molecule undergoes isomerization into the aci-form, followed by C3-N2 heterocyclic bond rupture. Both processes depend on temperature, resulting in an abnormally high value of the observed activation energy. [ DOI ]

Lure B. A., Smirnov S. P. Thermal decomposition of triaminoguanidinium nitrate // Combustion, Explosion, and Shock Waves. — 2002. — Vol. 38, no. 6. — P. 681–686. The kinetics of thermal decomposition of triaminoguanidinium nitrate (TAGN) was studied for the solid and liquid (solution) states of aggregation. The decomposition of crystalline powdered TAGN develops with severe self-acceleration. Its formal kinetic characteristics are determined. The main cause of the acceleration is the progressive melting of the solid during its thermal decomposition. The decomposition of TAGN in solution is severalfold faster than that in the solid state and proceeds at a rate decreasing with time. The main gaseous products of TAGN decomposition are N2, N2O, and H2O. The chemistry of the processes involved in TAGN decomposition are discussed. Key words: thermal decomposition, triaminoguanidinium nitrate, oxidizer. [ DOI ]
