The thermal behavior and non-isothermal decomposition kinetics of 1-amino-1-hydrazino-2,2-dinitro-ethylene potassium salt[K(AHDNE)] were studied under the non-isothermal conditions by different scanning calorimeter(DSC) method. The thermal behavior of K(AHDNE) presents three exothermic decomposition processes. The kinetic equation of the first thermal decomposition reaction obtained is dα/dT=(1019.63/β)3(1-α)[-ln(1-α)]2/3exp(-1.862× 105/RT). The self-accelerating decomposition temperature(TSADT) and critical temperature of thermal explosion(Tb) of K(AHDNE) are 162.5 and 171.4 °C, respectively. K(AHDNE) has higher thermal stability than AHDNE.
The thermal behavior and non-isothermal dissociation kinetics of 1-amino-1-hydrazino-2,2-dinitro-ethylene potassium salt [K (AHDNE)] were studied under the non-isothermal conditions by different scanning calorimeter (DSC) The thermal behavior of K (AHDNE) presents three exothermic decomposition processes. The kinetic equation of the first thermal decomposition reaction obtained is dα / dT = (1019.63 / β) 3 (1-α) [- ln /3exp(-1.862 × 105 / RT). The self-accelerating decomposition temperature (TSADT) and critical temperature of thermal explosion (Tb) of K (AHDNE) are 162.5 and 171.4 ° C, respectively. stability than AHDNE.
