Synthesis and Energetic Properties of Bis-(Triaminoguanidinium) 3,3′-Dinitro-5,5′-Azo-1,2,4-Triazolate (TAGDNAT): A New High-Nitrogen Material

This paper describes the synthesis and characterization of bis-(triaminoguanidinium)-3,3'-dinitro-5,5'-azo-1,2,4-triazolate (TAGDNAT), a novel high-nitrogen molecule that derives its energy release from both a high heat of formation and intramolecular oxidation reactions. TAGDNAT shows promise as a propellant or explosive ingredient not only due to its high nitrogen content (66.35 wt.-%) but also due to its high hydrogen content (4.34 wt.-%). This new molecule has been characterized with respect to its morphology, sensitivity properties, explosive, and combustion performance. The heat of formation of TAGDNAT was also experimentally determined. The results of these studies show that TAGDNAT has one of the fastest low-pressure burning rates (at 6.9 MPa) measured till date, 6.79 cm s(-1) at 6.9 MPa (39% faster than triaminoguanidinium azotetrazolate (TAGzT), a comparable high-nitrogen/high-hydrogen material). Furthermore, its pressure sensitivity is 0.507, a 33% reduction compared to TAGzT.
