Three salts of phenylenediammonium diperchlorate have been prepared and characterized by X-ray crystallography. Their thermal decomposition has been studied by thermogravimetry (TG), differential thermal analysis (DTA), and explosion delay (DE) measurements. The kinetics of thermal decomposition was evaluated by model fitting and isoconversional methods using TG data. The oxidation-reduction reactions near the surface of thermolysing perchlorates may be responsible for the decomposition followed by explosion. The possible pathways of thermolysis have also been proposed.
已制备出三种高氯酸苯二铵盐，并通过X射线晶体学对其进行了表征。通过热重分析（TG）、差示热分析（DTA）和爆炸延迟（DE）测量研究了它们的热分解。利用TG数据，通过模型拟合和等转化率方法评估了热分解动力学。热解高氯酸盐表面附近的氧化还原反应可能是导致分解继而爆炸的原因。还提出了可能的热解途径。
