摘要

The synthesis of 5,5'-diamino-3,3'-azo-1H-1,2,4-triazole (3) by reaction of 5-acetylamino-3-amino-1H-1,2,4-triazole (2) with potassium permanganate is described. Compound 3 is used as starting material for the synthesis of 5,5'-dinitrimino-3,3'-azo-1H-1,2,4-triazole (4), which was subsequently reacted with organic bases (ammonia, hydrazine, guanidine, aminoguanidine, triaminoguanidine) to form the corresponding nitrogen-rich triazolate salts (5-9). All substances were fully characterized by IR and Raman as well as multinu-clear NMR spectroscopy, mass spectrometry and differential scanning calorimetry. Selected compounds were additionally characterized by low temperature single crystal X-ray diffraction measurements. Detonation parameters (EXPLO5 code) were calculated based on CBS-4M computed heats of formation. The presented neutral compound as well as the tri-aminoguanidinium salt show detonation performances comparable to RDX. High thermal stabilities and low impact as well as friction sensitivities make the presented nitrogen-rich salts interesting for possible applications as insensitive HEDM.
