Synthesis and Properties of Guanidinium Salts of 5-(3-Aminofurazan-4-yl)tetrazol-1-ol

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 24J and friction sensitivity greater than 360N and decomposition temperature between 266 and 277℃, revealing good thermal stability.
