3,6-双(1-氢-1,2,3,4-四唑-5-氨基)-1,2,4,5-四嗪银盐的热分解反应动力学及热安全性
摘要:
利用两步合成法,得到标题化合物3,6-双(1-氢-1,2,3,4-四唑-5-氨基)-1,2,4,5-四嗪(BTATz)银盐(Ag2(BTATz)·2H2O),并用元素分析、X荧光和红外光谱分析对其进行了结构表征。采用DSC和TG-DTG技术对化合物进行热分解行为及非等温热分解动力学研究。结果表明,其热分解过程是由1个吸热阶段和2个放热阶段组成,主放热阶段的非等温热分解反应动力学方程为:dα/dt=1014.29×{3(1-α)[-ln(1-α)]1/4/4}exp(-2.10×104/T)。计算得到化合物的自加速分解温度(TSADT)、热爆炸临界温度(Tb)、热点火温度(TTIT)和绝热至爆时间(tTIAD)分别为517.10 K、580.12 K、531.00 K和90.32 s,以此来评价其热安全性。

Nonisothermal Decomposition Kinetics and Thermal Safety of Ag2(BTATz)·2H2O( BTATz=3,6-Bis(1-H-1,2,3,4 tetrazole-5-amino)-1,2,4,5-tetrazine)
Abstract:
The silver salt of 3,6-bis(1-H-1,2,3,4-tetrazole-5-amino)-1,2,4,5-tetrazine(BTATz)(Ag2(BTATz)·2H2O) was synthesized by two steps,and its structure was characterized by elemental analysis,X-ray fluorescence diffraction and FT-IR spectra. The thermal behavior of the compound was studied under non-isothermal conditions using DSC and TG-DTG methods,the result indicated that the thermal decomposition comprises of one endothermic and two exothermic stages,the non-isothermal decomposition reaction kinetics equation of the main exothermic stage can be expressed as:dα/dt=1014.29×{3(1-α)[-ln(1-α)]1/4/4} exp(-2.10 × 104/T). The values of the self-accelerating decomposition temperature(TSADT),critical temperatures of thermal explosion(Tb),thermal ignition temperature(TTIT) and the adiabatic time-to-explosion(tTIAD) for the compound were calculated as 517.10 K,580.12 K,531.00 K and 90.32 s,respectively. In addition,its thermal safety was evaluated.
