【 摘 要 】

A novel energetic combustion catalyst, 1, 8-dihydroxy-4, 5-dinitroanthraquinone nickel salt (DHDNENi), was firstly synthesized by the process of metathesis reaction in a yield of 91%, and its structure was characterized by IR, element analysis, thermogravimetric analysis (TG) and differential scanning calorimetry (DSC). The thermal behavior and non-isothermal decomposition reaction kinetics of DHDNENi were studied by means of different heating rate differential scanning calorimetry (DSC). The kinetic equation of major exothermic decomposition reaction for DHDNENi is obtained. The self-accelerating decomposition temperature (TSADT) and critical temperature of thermal explosion (Tb) are 574.4K and 593.4K, respectively. The thermal stability of DHDNENi is good.
