Research on the synthesis and properties of 2,4,6,8-Tetranitro naphthalene-1,5-diol and its three salts

This is the authors' abstract. We don't add key points for this paper.

2,4,6,8-tetranitronaphthalene-1,5-diol ( 4 ) and its three nitrogen-containing salts were synthesized. These energetic compounds were synthesized and characterized for the first time using multi-nuclear magnetic resonance spectroscopy, elemental analysis, and differential scanning calorimetry (TG-DSC). The crystal structure of compound 4 and its ammonium salt was determined using single-crystal X-ray diffraction at room temperature. Heats of formation (HOF) for the solid phase were calculated using the Gaussian software. Detonation parameters were estimated using the Explo5(V6.05.02)program. The sensitivities to impact and friction were also evaluated. The thermal decomposition temperature, densities, detonation velocities, detonation pressures, and impulse sensitivity values of these salts range from 233.9 to 269.6 °C, 1.75 to 1.83 g cm −3 , 7474 to 7864 m s −1 , 23.1 to 26.5 GPa, and 26 to 30 J, respectively.
