摘要：
A novel nitrogen-rich energetic compound 4-amino-1,2,4-triazole dinitroguanidine salt (4-ATDNG) was synthesized and fully characterized. Its crystal, thermal behaviour, and detonation properties were investigated by X-ray diffraction, thermogravimetry-derivative thermogravimetry-differential scanning calorimetry (TG-DTG-DSC) coupling system, and the Kamlet-Jacobs equation. In view of the obtained values such as the critical temperature of thermal explosion (T-b, 186.36 degrees C), entropy of activation (Delta S-not equal, 60.22 J mol(-1) k(-1)), enthalpy of activation (Delta H-not equal, 143.24 kJ mol(-1)), free energy of activation (Delta G(not equal), 116.34 kJ mol(-1)), detonation pressure (P, 29.78 GPa), detonation velocity (V, 8.28 km s(-1)), and impact sensitivity (h(50) = 135 cm), it is proposed that 4-ATDNG possesses excellent thermal stability and has the potential to be a useful energetic material in the future.
