✦ Synopsis
The new energetic material ammonium dinitramide (ADN), NH,N(NO,),, has been investigated with regard to its thermal properties and decomposition behaviour. Thermal decomposition of ADN is observed after complete melting at 91 S"C. The main decomposition pathway is based on the formation of NH,NO, and N,O followed by the thermal decomposition of NH,NO, to N,O and H,O at higher temperatures. Side reactions forming NO,, NO, NH,, N, and 0, are described and a mechanism for the acid-catalyzed decomposition of hydrogen dinitramide, dissociation product of ADN, is proposed.
