Abstract:Using self-synthetic 1, 4-diamino-3, 6-dinitropyrazolo[4, 3-c]pyrazole as raw material, a high energy material 1, 4-dinitramino-3, 6- dinitropyrazolo[4, 3-c]pyrazole(DNANP) was synthesized via the nitration. Its twelve organic energetic salts were prepared via the neutralization and metathesis reactions of DNANP and organic amine. The structures of target compounds were characterized by IR spectrometry, 1H NMR, 13C NMR, elemental analyses, mass spectrometry etc. The single crystal of DNANP·CH3COOH was obtained and the crystal structure was analyzed. The thermal performances of DNANP and its energetic salts were analyzed by DSC. The detonation performances of target compounds were predicted using CBS-4M method of Gaussian 09 program and Kamlet-Jacobs equations. Rsults show thate thermal decomposition peak temperatures of DNANP and its twelve energetic salts are 133.28, 176.66, 178.45, 155.52, 156.90, 144.78, 160.86, 155.60, 159.05, 198.90, 158.10, 173.06 ℃ and 157.41 ℃, respectively. Their densities are from 1.71 g·cm-3 to 1.92 g·cm-3, the detonation velocities are from 7.690 km·s-1 to 9.463 km·s-1 and the detonation pressures are from 25.9 GPa to 41.8 GPa, indicating that DNANP and its organic energetic salts are high energy density materials with good properties.
