3,4-Diamino-1,2,4-triazole based energetic salts: synthesis, characterization, and energetic properties was written by Wu, Jin-Ting;Zhang, Jian-Guo;Yin, Xin;Cheng, Zi-Yuan;Xu, Cai-Xia. And the article was included in New Journal of Chemistry in 2015.Synthetic Route of C4H3N3O4 This article mentions the following:
The protonation or metathesis synthesis and energetic properties of a new class of energetic materials, energetic salts of 3,4-diamino-triazole (DATr), are described. They were characterized by Fourier transform IR spectroscopy (FT-IR), elemental anal. (EA), differential scanning calorimetry (DSC), and X-ray single-crystal diffraction. The DSC results showed that these salts had acceptable thermal stabilities; the decomposition temperatures of these salts, except compound 3,4-Diamino-1,2,4-triazoliumnitro-formate, were over 200°. The d. of the series of salts ranged from 1.704 (3,4-Diamino-1,2,4-triazolium nitrate and 3,4-Diamino-1,2,4-triazolium picrate)-1.82 g cm-3 (3,4-Diamino-1,2,4-triazolium trinitrophloroglucinate), placing them in a class of relatively dense compounds, and the heats of formation were calculated with the Gaussian 03 suite of programs. All the salts except 3,4-Diamino-1,2,4-triazolium 4,5-dicarboxylic-1,2,3-triazolate exhibited promising detonation performances (detonation pressure: 21.5-32.8 GPa, detonation velocity: 7017-8620 m s-1), which were much higher than both those of TNT, and salt 3,4-Diamino-1,2,4-triazoliumnitro-formate was even comparable to RDX. Impact sensitivities were also determined by hammer tests and the results ranged from 8 J (sensitive) to > 40 J (insensitive). In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6Synthetic Route of C4H3N3O4).
1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) belongs to triazole derivatives. Triazoles are important five-member nitrogen heterocycles involved in a wide range of industrial applications such as agrochemicals, corrosion inhibitors, dyes, optical brighteners, as well as biologically active agents.Triazole heterocyclic structures are found to form many weak nonbond interactions with the receptors and enzymes in biological systems.Synthetic Route of C4H3N3O4
