Preparation of diazotetrazole

Preparation of diazotetrazole

5 grams of 5-aminotetrazole are dissolved in 30 ml of water containing 6 ml of 25% sodium hydroxide solution. To this solution 3.4 grams of sodium nitrite and 170 grams of crushed ice are added while the reaction flask is cooled with a salt-ice bath.  Slowly from dropping funnel 16 ml 30% of cold hydrochloric acid are added by not allowing the temperature to exceed 0° C. By the end of the diazotization the color of the solution becomes greenish. Diazotetrazole is very sensitive as even solution with greater concentration than 6-7% at 0° C decomposes explosively.
