Some common heterocyclic compound, 1455-77-2, name is 3,5-Diamino-1,2,4-triazole, molecular formula is C2H5N5, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. category: Triazoles
To a solution of 135.6 g (1.965 mol) of sodium nitrite in158.2 mL of water at -10 to -5 ¡ãC, we added a solution of 20 g(0.202 mol) of DAT in 423.7 mL 1.2 mol/L sulfuric acid for1.5 h. The reaction mixture was heated up to 60 ¡ãC and stirredfor another 1 h, then cooled the reaction mixture to roomtemperature. 67.2 mL 6 mol/L sulfuric acid and 11.85 g (0.121mol) aminosulfuric acid were added to reaction system andstirred for another 0.5 h, extracted with 322.5 ¡Á 3 mL of trioctylamineand 265.5 mL toluene, dried with magnesiumsulfate overnight. The magnesium sulfate was filtered and thefiltrate reacted with excess ammonia to obtain the yellow solid,dried in vacuum to give 25.1 g of 3,5-dinitro-1,2,4-triazoleammonium (AA DNT).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1455-77-2, its application will become more common.
