Abstract:
Five energetic metal salts are obtained from resorcinol and 3-hydroxy-2-nitropyridine by nitration, ammoniation and salification.The structures of these compounds are characterized by NMR and elemental analysis.The crystal structures of compound 4 · 4H
2O, compound 9 · 2H
2O and compound 10 are obtained by X-ray single crystal diffractometer.The crystal densities are 1.900, 1.808 and 2.008 g/cm
3, respectively.The thermal stabilities of these compounds are studied by differential scanning calorimetry (DSC) and thermogravimetry (TG), and their detonations and safety properties are also studied.The results show that the thermal decomposition temperatures of the five energetic metal salts are between 249℃ and 297℃, and the impact sensitivity is between 9 J and 33 J.The energetic metal salts with amino groups also have higher impact sensitivity values, which are greater than or equal to 29 J, respectively.The detonation test results show that none of these energetic metal salts can detonate RDX.
