1,3,3-Trinitroazetidine (TNAZ) is an explosive heterocyclic compound that has been considered as a potential replacement for TNT because of its low melting point (101 °C) and good thermal stability (up to 240 °C). TNAZ was first synthesized by Archibald et al. in 1990.[3] Several synthesis routes are known, and bulk production of several hundred kilogram batches has been demonstrated at Los Alamos National Laboratory.[4][1][5]
Properties
[edit]The compound crystallizes in an orthorhombic lattice with the space group Pbca. Thermolysis occurs starting around 240 °C - 250 °C with decomposition products that include nitrogen dioxide, nitric oxide, nitrous acid, carbon dioxide, and formaldehyde. It has a heat of decomposition of 6343 kJ/kg, and a detonation pressure of 36.4 GPa.[6]
