  • Continuous manufacture of DBX-1
    Patent number: 11312729
    Abstract: 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.
