Synthesis and characterization of a novel unsymmetncal azotetrazole compound with N_8 structure

摘要

A high-nitrogen compound, 5-(dinitromethylene)-1,4-bis((2,4-dinitrophenyl)diazenyl)-4,5-dihydro-1H-tetrazole, which can be obtained by N-azo coupling reactions from sodium 5-dinitromethyl-1H-tetrazolate with 2,4-dinitrophenyl diazonium salt solution. This type of Nitrogen-Nitrogen bonding formation provides a new pathway for discovery of novel high-nitrogen energetic compounds. The obtained compound was characterized by multinuclear NMR spectroscopy and IR spectroscopy. Its thermal stability properties were investigated using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
