Ammonium dinitramide (ADN) is a promising oxidizing agent for solid rocket propellants. In situ XRD investigations of ADN and suspensions have been performed in order to understand refine the emulsion crystallization process manufacturing spherical particles (prills). The investigation revealed that melt behavior depends on quality, humidity, maximum temperature cycles, suspension agents. Furth...

1-Amino-3-nitroguanidine (ANQ, 2) was synthesized via hydrazinolysis of nitroguanidine (1). An appropriate Lewis structure of ANQ is drawn based on VB calculations. Due to its basicity, it can be protonated by strong mineral acids or acidic heterocycles. In order to synthesize new energetic materials the nitrate (3) and perchlorate (4) salts of 1-amino-3-nitroguanidine were synthesized by proto...

The title compound, 1-carbamoylguanidinium bis-(2,4,6-tri-nitro-phen-yl)amide [H2NC(=O)NHC(NH2)2](+)[N{C6H2(NO2)3-2,4,6}2](-) (= guanylurea dipicryl-amide), was prepared as dark-red block-like crystals in 70% yield by salt-metathesis reaction between guanylurea sulfate and sodium dipicryl-amide. In the solid state, the new compound builds up an array of mutually linked guanylurea cations and di...

The thermal decomposition of ammonium dinitramide, NH4N(NO2)2 (ADN), in the gas phase has been studied at 373–920 K by pyrolysis/mass spectrometry under low-pressure conditions using a Saalfeld reactor. The reaction of the sublimed mixture of NH3 and HN(NO2)2 (dinitraminic acid, DN) was found to be initiated by the unimolecular decomposition of DN, HN(NO2)2 → HNNO2 ` NO2, followed by the rapid ...
