摘要

The energetics community desires improved methods to manufacture primary explosives safely.One example includes the manufacture of a highly valuable precursor sodium 5-nitrotetrazolate (NaNT).NaNT is the direct precursor to a novel primary explosive copper (I) 5-nitrotetrazolate (DBX-1). Thetraditional NaNT process has been plagued with microdetonations during processing, leading to reactordamage as well as increased stress to the operators. Previous investigators have reasoned that these smalldetonations occur during the diazotization reaction and caused by nitrogen oxide fumes arising from theprocess solution and reacting with droplets containing 5-aminotetrazole on various surfaces of theprocessing apparatus. Another challenge of the existing NaNT process is the isolation of the acid coppersalt intermediate on a filter. This intermediate is a sensitive energetic material and its isolation represents ahazard to operators, especially as reaction scale increases. There are engineering-focused methods beingdeveloped that completely avoid the acid copper salt (e.g. microreactors); however, these methods result inhigh inorganic impurities in NaNT, which impede the crystallization of DBX-1 in the subsequent reactionstep. Nalas has developed an alternative process to NaNT that addresses the majority of the processingchallenges and has been successfully demonstrated at the 600-ml scale and currently being scaled to the 5-liter scale.
