“…Desymmetrization of dimethyl carbonate, followed by condensation with glyoxal afforded bis(hydrazone) 27. Treatment with N-chlorosuccinimide (NCS), followed by displacement of the chlorines with azide, afforded diazido bis(hydrazone) intermediate (29). Acid-induced cyclization to give bis(tetrazole) (30), nitration of this species with dinitrogen pentoxide, and formation of the resultant dipotassium salt afforded K 2 DNABT.…”

Abstract:This review discusses the recent advances in the syntheses of high explosive energetic materials. Syntheses of some relevant modern primary explosives and secondary high explosives, and the sensitivities and properties of these molecules are provided. In addition to the synthesis of such materials, processing improvement and formulating aspects using these ingredients, where applicable, are discussed in detail.

“…It has been determined that MTX-1 is compatible with DBX-1 [34], RD-1333, KDNP [35], KDNBF, basic lead styphnate, calcium silicide, barium nitrate, antimony sulfide and PETN. It appears from the data that, as is the case with tetrazene (which forms hypersensitive silver azidotetrazole [36]), MTX-1 is not compatible with silver azide.…”

Tetrazene (1-amino-1(1H-tetrazol-5-yl)-azo-guanidine hydrate) is widely used in ordnance systems as a sensitizer of primer mixes for use in both percussion and stab applications. It has low thermal and hydrolytic stability compared with other components of primer mixes and there currently exists the need for a replacement with enhanced stability characteristics. MTX-1 (1-[(2E)-3-(1H-tetrazol-5-yl)triaz-2-en-1-ylidene]methanediamine) meets these criteria and shows great promise as a tetrazene replacement. Preliminary testing of this material has confirmed that MTX-1 has safety and performance properties which are similar to tetrazene and has chemical characteristics, including thermal and hydrolytic stability, which exceed those of tetrazene. MTX-1 has been successfully evaluated against tetrazene in a variety of chemical/output tests, including comparative testing in the PVU-12 primer.

A copolymer of chlorotrifluoroethylene and vinylidene fluoride was investigated to assess its viability as an oxidiser, for aluminium as the fuel, in an extrudable pyrotechnic composition for application in 3D printing. Experimental results and EKVI thermochemical modelling suggested that a fuel loading of 30 wt.% would provide the maximum energy output. DTA and TGA analysis were performed in order to ascertain processing limits. With the addition of a processing aid LFC-1 ® samples could be extruded successfully. Printing with the compositions had limited success. The high melt viscosity paired with the filament's susceptibility to excessive preheating caused the print quality to be low. Delamination did not occur due to good fusion achieved during layer deposition. With minor compositional adjustments printing quality could be improvedy.
