Trinitroazetidine (TNAZ)
1,1,3 Trinitroazetidine (TNAZ) is a material that is more powerful, but less-sensitive than HMX. The advent of the new high-energy explosive CL-20 and TNAZ present the possibility of increased performance high explosives with reduced sensitivity. A nitrogen-rich compound, TNAZ can itself be melted and moulded. But money was an issue. It costs just a few tens of dollars to produce a kilogram of HMX or RDX, but about $200 to create the same amount of TNAZ.
Most of the effort for producing the next generation of energetic materials is currently centered around the production of 1,3,3-trinitroazetidine (TNAZ). Researchers have evaluated five synthetic routes for producing TNAZ. The two most likely methods to manufacture TNAZ in a sustainable green manufacturing process are those due to Axenrod, and Coburn and Hiskey.
work funded by ARDEC led to the synthesis and process for the commercial scale-up of 3,3,1-trinitroazetidine (TNAZ), a strained ring Heterocyclic nitramine. TNAZ is one of the few new energetic materials found to be thermally stable above its melting point. However, in formulations studies, it has been found that TNAZ has high volatility that would severely inhibit its utility in military explosive and propellant applications. Further limitations to its use include the processing, polymorph, and material costs.
