摘　　要：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。The guanidinium(2),diaminoguanidinium(3),and guanidylguanidinium(4)salts of 5-(3-aminofurazan-4-yl)tetrazol-1-ol(1)were synthesized with a high yield using malononitrile as raw material,and their structures were characterized by IR,NMR,elemental analysis and thermal analysis.The single crystals of salts 2 and 3 were cultured and their structures were tested by X-ray single-crystal diffraction.The impact and friction sensitivities of three kinds of guanidinium salts were tested using the drop hammer method and friction sensitivity tester,and their thermal decomposition process was studied by DSC.The results show that three kinds of guanidinium salts exhibit the impact sensitivity greater than 24Jand friction sensitivity greater than 360Nand decomposition temperature between 266and 277℃,revealing good thermal stability.
