Abstract The thermal behavior and non‐isothermal kinetics of the exothermic decomposition reaction of 1‐amino‐1‐hydrazino‐2,2‐dinitroethylene (AHDNE) were studied with DSC and TG/DTG methods. The kinetic equation obtained is d α /d T =10 19.29 (1− α )exp(−1.88×10 4 / T )/ β . The critical temperature of thermal explosion is 98.16 °C. The specific heat capacity of AHDNE was determined, and the standard molar specific heat capacity is 211.86 J·mol −1 ·K −1 at 298.15 K. The adiabatic time‐to‐explosion of AHDNE was also calculated to be 59.21 s. AHDNE is unstable and has much lower thermostability than 1,1‐diamino‐2,2‐dinitroethylene (FOX‐7).
