White Crystalline powder | [Uses]
organic intermediate | [Application]
5-Aminotetrazole can be used as a propellant in pyrotechnic products, such as gas generators, airbags and smoke signal devices. Owing to its high nitrogen content (82 per cent) and high heat of combustion (208 kJ·mol⁻¹), it is often mixed with an oxidiser in practical applications. | [Flammability and Explosibility]
Notclassified | [Synthesis]
5-Aminotetrazole (5-AT) is synthesized by reacting cyanamide or dicyandiamide with an azide salt at high temperature in the presence of an acidic reagent (such as boric acid). The pKa value of this acidic reagent is between 3 and 7. The reaction solution is heated to above 75°C, preferably at reflux temperature (usually above 90°C). No large amounts of azide acid are generated during the reaction. After the reaction is complete, a strong acid (such as hydrochloric acid) is added to the reaction solution to acidify it, lowering the pH to below 3, causing the generated 5-AT to be protonated and precipitated. Finally, the pure 5-AT product is separated by conventional methods such as filtration and washing. The synthetic route is shown below:
