High-Nitrogen Compounds For Use in Low-Erosivity Gun Propellants
Abstract
Nitrogen rich compounds are suitable as ingredients in low smoke propellant charges. Several high-N energetic materials are presented which are based on tetrazoles. Tetrazoles are an unique class of compounds, since they combine a high nitrogen content and a high heat of formation with good thermal and kinetic stabilities due to their aromatic ring system. The reaction of 5-azidotetrazole with hydrazine yields hydrazinium 5-azidotetrazolate (1), which is the tetrazole salt with the highest nitrogen content (88.1 %) reported, yet. In addition ammonium and aminoguanidinium 5-azidoterazolate were synthesized and characterized. The detonation and propulsion parameter were calculated using the EXPLO5 program. In addition several outperforming tetrazole derivatives (N% > 80 %), which are currently under our investigation as additives in propellant charges, are presented. Using the heats of formation and the X-ray densities, the detonation parameter of hydrazinium 5-aminotetrazole, 5,5'- bis(1H-tetrazolyl)-hydrazine, 5,5'-bis(1H-tetrazolyl)- amine, 5,5'-bis(1-methyltetrazolyl)-triazene, 1,5-bistetrazole and its ammonium salt were calculated.
