一种新型吡唑并三嗪含能K-MOF的合成及性能
Synthesis and Properties of a New Pyrazolo-triazine-based Energetic K-MOF
摘要
Abstract
Energetic potassium 3,8-dinitro(pyrazolo[5,1-c][1,2,4]triazin-4-yl)nitramide(4)with a 3-dimensional metal-organic framework(3D EMOF)was synthesized via diazotization,cycloaddition and nitration by using 5-aminopyrazole(1)as raw material.Compound 4 was characterized and analyzed by nuclear magnetic resonance(NMR),Fourier infrared spec-troscopy(FT-IR),mass spectrometry(MS),single crystal X-ray diffraction(SC-XRD),and differential scanning calorimetry(DSC).The friction sensitivity and impact sensitivity of compound 4 were tested according to BAM standard.The detonation per-formance of compound 4 was predicted by EXPLO 5 software based on isodesmic reaction.Results show that the crystal of com-pound 4 belongs to monoclinic system,space groups P21/c,exhibits a 3-dimensional metal-organic framework(MOF)structure with a density of 2.021 g·cm-3 at 150 K.Compound 4 has a thermal decomposition temperature of 203.4℃,a theoretical deto-nation velocity of 8717 m·s-1,a theoretical detonation pressure of 33.5 GPa,a friction sensitivity of 168 N,and an impact sensi-tivity of<3 J.关键词
