Synthesis and Charaterization of 3,5,7-Triamino[1,2,4]triazolo[4,3-a][1,3,5]triazine Pentazolate Salt
摘要
Abstract
A novel nonmetallic salt,3,5,7-triamino[1,2,4]triazolo[4,3-a][1,3,5]triazine pentazolate(4),was synthesized through a metathesis reaction by employing AgN5 as precusor with 3,5,7-triamino[1,2,4]triazolo[4,3-a][1,3,5]triazine hydro-chloride.The structural characterization were carried out by X-ray single crystal diffraction,infrared spectroscopy(IR),elemen-tal analysis(EA),nuclear magnetic resonance(NMR),and thermal decomposition behavior were determined by thermogravi-metric analysis(TG)and differential scanning calorimetry(DSC).The enthalpy of formation of compound 4 was calculated us-ing atomization method,the detonation performance was predicted using EXPLO5,and sensitivity was tested using BAM testing method.The results show that compound 4 exhibits a monoclinic crystal structure with a crystal density of 1.644 g·cm-3 and be-longs to the P21/n space group.This compound has a nitrogen content of 77%,a thermal decomposition temperature of 113.8℃,and an enthalpy of formation of 491.5 kJ·mol-1.Furthermore,its detonation velocity was calculated at 7913 m·s-1,detonation pressure at 19.6 GPa;The impact sensitivities measured were>40 J,and friction sensitivity>360 N.关键词
