摘要
Abstract
Using 4,4',5,5'-tetranitro-2H,2'H-3,3'-bipyrazole(TNBP)as the starting material,compound 1 was synthesized by reacting with a base.Furthermore,compound 1 was used as the starting material to synthesize metal salt compounds 2-6 of the compound through metathesis reactions.The structures of the compounds were characterized by infra-red spectroscopy,carbon spectroscopy of nuclear magnetic resonance,and elemental analysis.Further structural characte-rization of compound 1 was conducted using single-crystal X-ray diffraction.Thermal behavior of compounds 1-6 was stud-ied using differential scanning calorimetry(DSC).The thermal decomposition temperature of compounds 1-6 ranges from 280℃to 336℃.The thermodynamic parameters of TNBP metal salts were determined using Kissinger kinetic equation.The detonation properties of compounds 1-6 were evaluated using Gaussian 09 and Explo 5 programs,with calculated deto-nation velocities ranging from 7 119 m/s to 8 654 m/s,detonation pressures ranging from 26.8 GPa to 39.45 GPa,and detonation heats ranging from 5 262 J/g to 8 827 J/g.Sensitivity tests performed using a BAM impact sensitivity tester indi-cated that the impact sensitivities of compounds 1-6 ranged from 5 J to 7 J,and their friction sensitivities ranged from 40 N to 60 N.关键词
