Synthesis and Energetic Properties of N-Substituted 3,4-and 3,5-Dinitropyrazoles

3,4- and 3,5-Dinitropyrazoles(DNPs) were substituted with acryland allyl groups on the N1 nitrogen atom, resulting in three novelenergetic materials. These compounds are all liquids at room temperaturewith melting points ranging from -60.2 to -38.6 degrees Cand were fully characterized by high-resolution mass spectrometry,elemental analysis, proton and carbon nuclear magnetic resonance spectroscopy,and Fourier transform infrared spectroscopy. These materials werealso tested for electrostatic discharge, friction, and impact sensitivitiesand then compared to DNP starting materials and to the explosive nitroglycerin(NG). These results indicate that the synthesized compounds are lesssensitive to impact compared to NG and have higher thermal stabilitiesto decomposition.

Automated summary

Three novel energetic materials were synthesized, which are liquids at room temperature with melting points ranging from -60.2 to -38.6 degrees C. They were fully characterized and compared to the starting materials and nitroglycerin in terms of sensitivity to impact and thermal stability.
