摘要

2-Methyl-5-nitraminotetrazole (1) was formed by nitration of 2-methyl-5-aminotetrazole. 2-Methyl-5-aminotetrazole was obtained by methylation of sodium 5-aminotetrazolate. Nitrogen-rich salts such as guanidinium (2), 1-aminoguanidinium (3), 1,3-diamino-guanidinium (4), 1,3,5-triamino-guanidinium (5), azidoformamidinium 2-methyl-5-nitriminotetrazolate (6) as well as an urea adduct (7) were prepared by facile deprotona-tion or metathesis reactions. All compounds were fully characterized by single crystal X-ray diffraction, vibrational spectroscopy (IR and Raman), multinuclear NMR spectros-copy, elemental analysis and DSC measurements. The heats of formation of 2-7 were calculated using the atomization method based on CBS-4M enthalpies. With these values and the experimental (X-ray) densities several detonation parameters such as the detona-tion pressure, velocity, energy and temperature were computed using the EXPL05 code. In addition, the sensitivities towards impact, friction and electrical discharge were tested us-ing the BAM drop hammer, a friction tester as well as a small scale electrical discharge device.
