A method of manufacture of the primary explosive material copper(I) 5-nitrotetazolate (DBX-1) by a synthesis starting with 5-aminotetrazolate (5-AT); wherein, the synthesis provides intermediates acid copper salt of 5-NT and sodium 5-nitrotetrazolate (NaNT) sodium 5-nitrotetrazolate (NaNT)—that are both, free of any 5-aminotetrazolate (5-AT) starting material—such that the subsequent production of the DBX-1 is not inhibited. Further, this method utilizes an internal filter within the reactor—to minimize handling of explosively dangerous intermediates.

the oxidation of 5‐amino‐1H‐tetrazole (5‐AT) to 5‐nitrotetrazole (5‐NT) in high yields in a single‐pot synthesis. This strategy reduces the synthesis of this important energetic material down to a single step and eliminates highly sensitive diazonium and copper salt primary explosive intermediates. Use of dimethyl sulfoxide along with molecular sieves and 18‐crown‐6 as phase transfer catalyst promoted

Sodium 5-nitrotetrazolate dihydrate (NaNT) is a useful precursor compound for the synthesis of lead-free primary explosives; however, currently employed syntheses for the compound are tedious, dangerous, and plagued by impurities. Through comprehensive analysis, we elucidate the identity of the most detrimental impurities and further report an improved procedure for preparation of NaNT, which greatly

The present invention is directed to a process for continuous production of copper (I) nitrotetrazolate (DBX-1) by reacting aqueous copper salt with aqueous 5-nitrotetrazolate salt in the presence of a reducing agent. All the reactants are introduced into a continuous flow reactor system, which is composed of a temperature controlled tubular reactor and a mixer that allows for radial mixing. An optional stirred tank reactor may also be incorporated into the process to complete the reaction and allow for crystal growth.
