以丙二腈为原料,高收率合成了5-(3-氨基呋咱-4-基)-1-羟基四唑(1)的胍盐(2)、二氨基胍(3)以及联胍盐(4)。采用红外光谱、核磁共振、元素分析、热分析等对其结构进行了表征;培养了2和3的单晶,并采用X射线单晶衍射测试了其晶体结构;通过落锤法和摩擦感度仪测试了3种胍盐的撞击感度和摩擦感度;采用DSC研究了3种胍盐的热分解过程。结果表明,3种胍盐的撞击感度均大于24J,摩擦感度均大于360N,分解点介于266~277℃,显示出良好的热稳定性。
Using malononitrile as the starting material, the guanidinium salt (2) of 5- (3-aminofurazan-4-yl) -1-hydroxytetrazole (1), diaminoguanidine (3) and guanidine Salt (4). Its structure was characterized by infrared spectroscopy, nuclear magnetic resonance, elemental analysis and thermal analysis. Single crystals of 2 and 3 were cultured and their crystal structures were tested by X-ray single crystal diffraction. The impact sensitivities and friction sensitivities of three guanidinium salts were tested. The thermal decomposition of three guanidinium salts was investigated by DSC. The results showed that the impact sensitivities of the three kinds of guanidinium salts were both greater than 24J, the friction sensitivities were both higher than 360N and the decomposition points were between 266 and 277 ℃, showing good thermal stability.
