Owing to splendid properties, trinitrophenol-based ionic liquid consisting of ammonium–imidazolium cation, 3,5-diamino-1,2,4-triazole picrate (DATPA), has been investigated concerning the thermal stability in this study. Differential scanning calorimeter (DSC) and thermogravimetry (TG) are used to explore the thermal behavior such as melting point, decomposition temperature, and the temperature of 10% mass loss which are the target to evaluate the thermal stability of other two picrates (picrate and 4-amino-1,2,4-triazole picrate). The results show that DATPA has better thermal stability at 251–252 °C than the other two picrates, and the melt volatility has decreased as well. Moreover, thermal kinetics parameters are calculated by changing the heating rates of DSC and TG. ASTM standard E698 and Kissinger methods are utilized to calculate, and double extrapolation is accepted to explore the mechanism function in the decomposition course, which has been defined as \(f(\alpha ) = 2.105(1{-}\alpha )[\ln (1{-}\alpha )]^{0.525}\) in this study. Finally, an accelerating rate calorimeter is employed to study the thermal hazard of DATPA under the adiabatic condition and evaluate the level of runaway reaction through the risk matrix. According to Townsend method, we achieve the thermal kinetics parameters of DATPA under adiabatic condition. The results show that the apparent activation energy (E_a) of DATPA is 273.2 kJ mol⁻¹ higher than many other explosives. Besides, according to the theoretical calculation, we find that DATPA has good detonation properties with high stability.

由于具有出色的性能，在此研究中，对由铵-咪唑鎓阳离子，3,5-二氨基-1,2,4-三唑苦味酸盐（DATPA）组成的基于三硝基苯酚的离子液体进行了研究。差示扫描量热仪（DSC）和热重分析仪（TG）用于探索热行为，例如熔点，分解温度和10％质量损失温度，这是评估其他两种苦味酒（苦味精和苦味精）的热稳定性的目标。 4-氨基-1,2,4-三唑苦味酸酯）。结果表明，DATPA在251–252°C时比其他两种苦味酸盐具有更好的热稳定性，并且熔体挥发性也有所降低。而且，通过改变DSC和TG的加热速率来计算热动力学参数。ASTM标准E698和基辛格方法用于计算，本研究中的\（f（\ alpha）= 2.105（1 {-} \ alpha）[\ ln（1 {-} \ alpha）] ^ {0.525} \）。最后，采用加速量热仪研究绝热条件下DATPA的热危害，并通过风险矩阵评估失控反应的程度。根据Townsend方法，我们获得了绝热条件下DATPA的热力学参数。结果表明，DATPA的表观活化能（E _a）比许多其他炸药高273.2 kJ mol ^-1。此外，根据理论计算，发现DATPA具有良好的爆轰性能和较高的稳定性。
