Reaction Steps

U.S. Pat. No. 6,040,453 A discloses a process for preparing the diammonium salt of 5,5′-bi-1H-tetrazole using dicyan, sodium azide, ammonium chloride, and water as reaction medium. The process sees the dicyan added at low temperature to an aqueous solution comprising sodium azide and ammonium chloride. The mixture is subsequently heated. The 5,5′-bi-1H-tetrazole diammonium salt that is formed in this process is precipitated in the form of crystals that are of low solubility.
