摘要
Abstract
To obtain high-performance energetic materials,3,5-diamino-1,2,4-triazole was utilized as a raw material to syn-thesize 3-hydrazinyl-5-amino-1H-1,2,4-triazolium dihydrochloride(compound 1)through diazotization and reduction reac-tions.A novel energetic ionic salt,3-hydrazinyl-5-amino-1H-1,2,4-triazolium dinitrate(compound 2),was prepared by the metathesis reaction of compound 1 with silver nitrate.The structure of compound 2 was characterized using various techniques including FTIR,NMR,mass spectrometry,elemental analysis,and single-crystal X-ray diffraction.Thermal decomposition of compound 2 was studied by DSC and TG.The contribution of hydrogen bonding to the intermolecular interactions in the crystal of compound 2 was calculated using Crystal Explorer software.The detonation and safety properties of compound 2 were also investigated.The results show that compound 2 belongs to monoclinic crystal system with space group P2/n and cell parame-ters a=6.929 6 Å,b=9.9082 Å,c=13.369 6 Å,α=90.00°,β=103.51(2)°,γ=90.00°,V=892.54(11)Å3.It exhib-its excellent thermal stability with a thermal decomposition temperature of 189.7 ℃.Furthermore,compound 2 demonstrates outstanding detonation performance and low sensitivity,with detonation velocity and pressure values of 8 673 m/s and 32.5 GPa,respectively.The friction sensitivity and impact sensitivity are 112 N and 25 J,respectively.关键词
