A new unsymmetrical s‐tetrazine derivative, namely 4‐(2‐[6‐(3,5‐dimethyl‐1H‐pyrazol‐1‐yl)‐1,2,4,5‐tetrazin‐3‐yl]hydrazin‐1‐ylidene}methyl)phenol (DPHM), C14H14N8O, was synthesized based on 3‐(3,5‐dimethylpyrazol‐1‐yl)‐6‐hydrazinyl‐s‐tetrazine (DPHT). The structure was characterized by elemental analysis and single‐crystal X‐ray diffraction. Crystal structure determination shows that DPHM crystallizes
一种新的不对称s-四嗪衍生物,即4-(2- [6-(3,5-二甲基-1 H-吡唑-1-基)-1,2,4,5-四嗪-3-基]肼基于3-(3,5-二甲基吡唑-1-基)-6-肼基-s-四嗪(DPHT)合成了-1-亚甲基}甲基)苯酚(DPHM),C 14 H 14 N 8 O. 通过元素分析和单晶X射线衍射对结构进行了表征。晶体结构的确定表明,DPHM在单斜P 2 1 / c空间群中以高共面性和之字形层状结构结晶。此外,通过DSC和TG–DTG方法研究了其热行为。DPHM的热安全性通过自加速分解温度(T SADT),热爆炸的临界温度(T b),活化熵(ΔS),活化焓(ΔH)和活化自由能(ΔG)。同时确定了DPHM的动力学参数和比热容。结果表明,由于引入了DHBTz,DPHM具有比3-(2-苄叉肼基-1-基)-6-(3,5-二甲基吡唑-1-基)-四嗪(DAHBTz)更好的稳定性和爆轰性能。羟基,增
