Nitrogen-rich heterocycles are of great interest for the design high-energy materials (HEMs) because they offer high density, positive heat formation, superior detonation properties, and thermal stability. Among different types nitrogen-rich heterocyclic azoles, 1,2,4-triazole provides a remarkable framework development green energetic materials. The presence functional groups, such as nitro, amino, nitramino affects stability, decomposition behavior, properties HEMs. In present study, we chose amino- substituted triazole containing both amino carboxymethyl groups to compare their mechanisms. pathways 3-amino-1,2,4-triazole (1), 2,4-dihydro-3H-1,2,4-triazol-3-ylidene-nitramide (2), 5-amino-1,2,4-triazol-3-yl-acetic acid (3) were explored using experiments mass spectrometry. Kinetic parameters evaluated nonlinear integral method, elucidated based on fragmentation data obtained from spectrometry tandem Furthermore, near-real-time identification products that evolved in form gases was performed TG-FTIR technique. Based kinetic analysis, data, possible degradation HEMs following introduction substituents identified.

Thermal stability is one of the most significant properties for safety energetic materials, finding a stable skeleton with suitable groups always primary test. In this work, an unusual aminohydrazone cyclization strategy was used in synthesis new series gem-dinitro 1,2,4-triazolo[4,3-b][1,2,4,5]-tetrazine compounds desirable thermal (≥197 °C). All were fully characterized by infrared (IR), NMR, differential scanning calorimetry, single crystal X-ray diffraction, and elemental analysis. The decomposition temperature potassium salt 2 288 °C, reaching level HMX. these performances have demonstrated effective innovatively combining geminal dinitro fused rings.

In order to discover of high-energy materials with characteristics that surpass modern benchmarks, it is necessary study the widest range potential structures. The design energetic compounds using high-nitrogen cage scaffolds provides new opportunities. One promising representatives polycyclic multinitragen cages hexaazaisowurtzitane, since most powerful explosive CL-20 based on it. recent years, synthesis analogues has been actively developed. This review presents progress in synthesis, performance and structure-property relationship for polynitro hexaazaisowurtzitanes over past decade.
