Example Embodiment
[0021] Add 2.54g (10mmol) of 3,3'-dinitro-5,5'-azo-1H-1,2,4-triazole and 50ml of water to a 100ml single-neck flask equipped with magnetic stirring, and heat to Dissolve, then quickly add (3.40g, 10mmol) silver nitrate, stir for 1h in the dark, and filter to obtain a yellow solid 3,3'-dinitro-5,5'-azo-1H-1,2,4-tri Silver azole salt 4.30g, yield 92%; elemental analysis: C 4 Ag 2 N 10 O 4 (467.84) (%) Calculated value: C 10.27, H 0.00; N 29.94; measured value: C10.09, H0.08, N 29.71.
[0022] 467 mg (1 mmol) of 3,3'-dinitro-5,5'-azo-1H-1,2,4-triazole silver salt was added to 107 mg (2 mmol) of ammonium chloride aqueous solution (50 mL). Stir at 80°C for 4h, and filter off the AgCl precipitate while it is hot. The filtrate was evaporated to dryness and recrystallized with water. After drying, 219 mg of 3,3'-dinitro-5,5'-azo-1H-1,2,4-triazole diammonium salt was obtained, with a yield of 76%. Decomposition temperature: 248°C (DSC, heating rate 5°C / min). IR(neat): 3255,2962,2835,16...
