摘要
介绍了一种合成偶氮四唑二胍（GZT）的合成路线，利用元素分析和红外分析对产物进行了表征，确定其为目标产物。利用TG—DTA分析了GZT的热力学性能，对其摩擦、撞击感度进行了测试，用ARC对其与氧化剂的配方进行了测试。测试结果发现，GZT在249～257．9℃之间失重约为62．2％．对摩擦和撞击均钝感，具有良好的热稳定性，分解产生大量气体。分析显示GZT是一种具有潜在应用前景的低特征信号推进剂添加剂。
A synthesis route of guanidinium azotetrazolate（GZT） is introduced. The product was characterized and determined as the title compound by element analysis and IR analysis. Thermodynamic performance of GZT was analyzed by TG-DTA, and its friction sensitivity and impact sensitivity were tested. Formulation of GZT and oxidant was tested by ARC. Test resulls show that GZT loses weight about 62.2% between 249-257.9 ℃, possesses low sensitivity to friction and impact, a good thermal stability, and a large amount of gas generated from decomposition. Analysis results of GZT show that it is a low characteristic signal propellant additive with potential application prospect.
