제목 Synthesis of bis(dinitoropyrazolyl)methanes as potential insensitive high energy materials
초록 High explosive performance and insensitivity are essential characteristics of high energy materials (HEMs) that have been developed in recent years. Explosive performances of energetic materials are influenced by their molecular structure, heat of formation and nitrogen ratio in molecule. Recently, polynitropyrazoles, which have excellent properties in both stability and explosion performance, are attracting attention as new energetic materials.
The two new symmetric bis(dinitropyrazole)s, bis(3,4-dinitropyrazol-1-yl)methane and bis(3,5-dinitropyrazol-1-yl)methane were synthesized from commercially available 1H-pyrazole in overall 72% and 42% yields, respectively. Their measured data show both high thermal stability and low sensitivity. They are expected to be available as precursors of new HEMs.
