TNAZ = Trinitroazetidin

In a similar synthetic route, the strong oxidizers TNAZ (trinitroazetidine) and CL-20 were prepared (Fig. 1.7). 

Fur das Trinitroazetidin werden mehrere Syntheserouten beschrieben, z. B. aus Epichlorhydrin und tert. Butylamin zum 1-tert.-Butylazetidin und anschlieliender, stufenweisen Nitrierung zum TNAZ. 

TNAZ (2.19) is also known as 1,3,3-trinitroazetidine (C3H4N406) and was first prepared in 1983 at Fluorochem Inc. It is reported to be more thermally stable than RDX but more reactive than HMX. Pure TNAZ is more shock sensitive than the explosives based on HMX but less sensitive than analogous PETN. It can be used as a castable explosive and as an ingredient in solid rocket and gun propellant.

Several synthetic routes for trinitroazetidine have been described, e.g. from epichlorhydrin and tert. butylamine to give 1-tert.-butylazetidine and subsequent stepwise nitration to yield TNAZ.
