2, 6-Bis(picrylamino)-3, 5-dinitropyrazine(BPNP), a new energetic compound, was synthesized with a total yield of 47% from 2, 4, 6-trinitrochlorobenzene and 2, 6-diaminopyrazine via condensation and nitration. The structure of BPNP was characterized by infrared(IR) spectroscopy, nuclear magnetic resonance(NMR) and mass spectrometer(MS). The yield of condensation was the highest, while the optimal solvent was isopropanol and the optimal catalyst was pyridine. The effect of the nitrition was the best, while the volume ratio between H₂SO₄ and HNO₃, reaction temperature and reaction time were V(H₂SO₄):V(HNO₃)=4:1, 50 ℃ and 3 h, respectively. The decomposition temperature of BPNP is 374.3 ℃, which was investigated by thermogravimetry(TG) and differential scanning calorimetry(DSC). The theoretical density of BPNP after optimizing predicted by Monte-Carlo method is 1.82 g·cm^-3. The detonation velocity and detonation pressure predicted by Kamlet-Jacobs formula are 8.13 km·s ^-1 and 28.25 GPa. H₅₀ of impact sensitivity predicted by electrostatic potential is 83 cm. All the results show that BPNP has higher detonation pressure than PYX, and has potential value in application and research.
