摘要 利用3-硝基-1,2,4-三唑-5-酮的钠盐(NaNTO.H2O)和盐酸胍在水溶液中合成了一种新型含能材料NTO胍盐(GNTO)。采用DSC和TG/DTG法对GNTO进行了热行为及非等温热分解动力学研究,其热分解反应的动力学方程为dαdT=102β3.716(1-α)32[1-(1-α)31]21exp(-2.602×105/RT),临界爆炸温度为256.29℃。同时,利用微量热法对GNTO的比热容进行了测定,298.15 K时GNTO的标准摩尔比热容为236.88 J/(mol.K);计算得到了GNTO的绝热爆炸时间为102.16 s。 3-Nitro-1,2,4-triazol-5-one guanidine salt(GNTO) was synthesized by the reaction of NaNTO·H2O and guanidinium chloride solution in water at 60℃. The thermal behavior and non-isothermal decomposition kinetics of GNTO were researched by using DSC and TG/DTG methods. The obtained kinetic equation is dα/dT=10^23.71/β 6(1-α)^2/3[1-(1-α)^1/3]^1/2 exp(-2.602×10^5/RT). The critical temperature of thermal explosion is 256.29 ℃. The specific heat capacity of GNTO was determined by means of micro-DSC method and the standard molar specific heat capacity is 236.88 J/( mol.K) at 298.15 K. The calculation results show that adiabatic time-to-explosion of GNTO is 102.16 s.
