Synthesis and Characterization of a Novel High Nitrogen Energetic Compound 5-((5-Nitro-2H-tetrazol-2-yl)Methyl)-1H-tetrazol-1-ol

Using 5-aminotetrazole as starting material, a novel high nitrogen energetic compound 5-((5-nitro-2H-tetrazol-2-yl)methyl):1H-tetrazol-1-ol was synthesized with a total yield of 19% via diazotization-nitration, alkylation, oximation, diazotization-chlorination, azidation and cyclization. It was characterized by NMR, MS, IR and elemental analysis. The crystal structure of this compound was determined by X-ray single crystal diffraction analysis. The results indicated that it belonged to monoclinic system with space group. P2(1), and the crystal parameters were a=3.3619(11) angstrom, 6=9.3910(19) angstrom, c= 8.2060(16) angstrom, beta=101.44(3)degrees, Z=2, D-c= 1.748 g.cm(-3), mu=0.153 mm(-1), F(000)=216. The thermal properties were studied by differential scanning calorimeter (DSC) and thermogravimetric (TG) analyzer analyses, which showed that the decomposition temperature of target compound was 202.25 degrees C, and the mass loss due to overall reaction (130 similar to 320 degrees C) was 78.6%. The detonation velocity and detonation pressure of this compound calculated by Kamlet-Jacobs formula are 8500 m.s(-1) and 31.53 Gpa, respectively.
