【 摘 要 】

A new high-energy organic potassium salt, 2-(dinitromethylene)-1,3-diazepentane potassium salt K(DNDZ), was synthesized by reacting of 2-(dinitromethylene)-1,3-diazepentane (DNDZ) and potassium hydroxide. The thermal behavior and non-isothermal decomposition kinetics of K(DNDZ) were studied with DSC, TG/DTG methods. The kinetic equation is d�?/dT = 10^13.92/�?*3(1-�?)[-ln(1 - �?)]^2/3 exp(-1.52 �? 10⁵ / RT). The critical temperature of thermal explosion of K(DNDZ) is 208.63 oC. The specific heat capacity of K(DNDZ) was determined with a micro-DSC method, and the molar heat capacity is 224.63 J mol^-1 K^-1 at 298.15 K. Adiabatic time-to-explosion of K(DNDZ) obtained is 157.96 s.
