Non‐isothermal Decomposition Kinetics, Specific Heat Capacity and Adiabatic Time‐to‐explosion of 1‐Amino‐1‐hydrazino‐2,2‐dinitroethylene (AHDNE)

Abstract

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 dα/dT=1019.29(1−α)exp(−1.88×104/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).
