Thermal decomposition behavior and thermal stability of DABT·2DMSO

摘要: The thermal decomposition behavior and stability of 3,3′-diamino-5,5′-bis(1H-1,2,4-triazole) with 2DMSO (DABT·2DMSO) were investigated by thermo gravimetry–derivative gravimetry–differential scanning calorimetry (TG–DTG–DSC), differential analysis (DTA) accelerating rate calorimeter (ARC). result TG–DTG–DSC at a heating 10 °C min−1 indicated that an endothermic exothermic occurred 388.23 468.23 °C, respectively. apparent activation energy (E a) pre-exponential factor (A) the decomposition, free activation, enthalpy entropy initial temperature (T p0) calculated from DTA curves recorded rates 1, 2, 4, 8 °C min−1. critical explosion bp0) obtained Ozawa’s Kissinger’s methods as 470.46 470.73 °C, ARC self-heating started 443.61 °C ended 480.91 °C, within time span 1397.50 min. parameters, including onset temperature, final max rate, adiabatic rise to maximum obtained, these parameters corrected inertia factor. E A under condition also calculated. In addition, self-accelerating SADT, 50kg) was 429.54 °C.
