Synthesis and characterization of 3,4-dinitropyrazole

    Abstract
  • Nitro-heterocyclic compounds are good candidates for developing new insensitive high-energy explosives with low melting points. A new nitro-heterocyclic compound, 3,4-dinitropyrazole (DNP), was synthesized. With low melting point, it can be used as an explosive. The compound was characterized by IR, elemental analysis, mass spectrometry and nuclear magnetic resonance spectroscopy. Its thermal decomposition and phase change were also analyzed with DSC and its melting point was 85-87.℃. Because of its low melting point and good thermal stability, DNP could be used for the design of novel insensitive melt-cast explosive.
