Promising Oxygen- and Nitrogen-Rich Azidonitramino Ether Plasticizers for Energetic Materials

Abstract

A simple, mild and general method has been developed for the preparation of alkyl nitramines bearing a halogenoalkoxylic moiety. From these reactive halogen intermediates, a few azidoalkoxyl alkyl nitramines have been produced as energetic plasticizers. This simple protocol allows azidonitramino ether plasticizers to be obtained from available precursors in high yields, as it is safe and viable for large-scale operations. The resulting products have been fully characterized by spectral methods, and their impact sensitivity, thermal transformations and burning properties were determined, thus allowing complete comparison to the analogues including other combinations of structural units. Such characterization of these new plasticizers illustrates the extent to which the nature and position of the functional units can be used to tune the above properties of these nitramines. All azidonitramino ethers are liquid with excellent energetic performance and are promising candidates for new environmentally friendly energetic materials.

Energetic Polymer Possessing Furazan, 1,2,3-Triazole, and Nitramine Subunits

“…The limit of compatibility of polymer 12 with diethylene glycol dinitrate (DEGDN) is 20% (12: DEGDN = 80:20, T g = 2 • C, Figure 11). Not only nitroesters such as NG and DEGDN, but also organic azides [2,65,66] such as Z1, Z3, Z8, and Z12 (Figure 12) were used to plasticize polymer 12. The use of azide plasticizers allows to reduce the combustion temperature of the binder including them in comparison with compositions based on nitro ester plasticizers.…”

Synthesis, Characterization, and Properties of High-Energy Fillers Derived from Nitroisobutylglycerol

“…Among them, the compounds with high thermal stability and low impact sensitivity are of particular interest [5,6]. It should also be noted that particularly low-molecular-weight fillers are especially promising for applications due to their simple affordable synthesis resulting in an excellent price/performance ratio [7,8].…”
