THE NEW ENERGETIC MATERIAL AMMONIUM DINITRAMIDE AND ITS THERMAL DECOMPOSITION

摘要

The new energetic material ammonium dinitramide (ADN), NH4N(NO2)(2), has been investigated with regard to its thermal properties and decomposition behaviour. Thermal decomposition of ADN is observed after complete melting at 91.5 degrees C. The main decomposition pathway is based on the formation of NH4NO3 and N2O followed by the thermal decomposition of NH4(N)O(3) to N2O and H2O at higher temperatures. Side reactions forming NO2, NO, NH3, N-2 and O-2 are described and a mechanism for the acid-catalyzed decomposition of hydrogen dinitramide, dissociation product of ADN, is proposed. [References: 10]
