Abstract : A process for preparing the acid copper salt of 5-nitrotetrazole by slowly adding an aqueous solution of a strong inorganic acid (e.g., h2SO4 or HNO3), 5-aminotetrazole, and a small amount of a water soluble cupric salt (e.g. CuSO4-5H2O) to an aqueous solution of a water soluble cupric salt (e.g., CuSo4-5H2O) sodium nitrite in a 25 to 100 percent stoichiometric excess. The presence of the cupric salt in the initial 5-aminotetrazole, acid solution prevents the occurrence of minor explosions and the large excess of sodium nitrate produces an easily filtered product rather than a gel. The acid copper salt of nitrotetrazole is used in the preparation of mecuric 5-nitrotetrazole which is useful as a primary explosive in detonators. (Author)
