“…For example, the sensitivity of MF is mostly reported as being from 0.4 J to 1.2 J [3]; we obtained 0.62 J. PETN is mostly reported as being between 3 J and 4.1 J [3]; 50% probability of initiation determined in the present study was 3.93 J. …”

4,6-Diazido-N-(2,4,6-trinitrophenyl)-1,3,5-triazin-2-amine (TNADAzT) and its silver salt (AgTNADAzT) were prepared and characterized. Elemental analysis, FTIR, NMR, DSC, AAS and X-ray diffraction were used for analytical characterization. The sensitivities of TNADAzT and AgTNADAzT were determined and compared with common explosives and MTX-1. The crystal density of TNADAzT is 1.794 g·cm −3 and its heat of formation 899 kJ·mol −1 . The sensitivity of TNADAzT to impact and friction slightly exceeds PETN; the sensitivity to electrostatic discharge is lower than RDX. The sensitivity of AgTNADAzT is on the level of a primary explosives (between mercury fulminate and PETN). The initiation efficiency of AgTNADAzT is higher than 200 mg (acceptor PETN compressed by 64-70 MPa) and therefore excludes it from practical use as a primary explosive in detonators.

“…The results of the electric spark sensitivity tests are presented in Table 4. TNADAzT is significantly less sensitive to electric discharge than PETN and RDX; the sensitivity of its silver salt is lower than that of MF and comparable with that of lead azide [3]. …”

“…It is commonly agreed that the highly toxic mercury fulminate (1), adopted for use in some of the first percussion primer formulations in the early 1800s [6] and later by Alfred Nobel for some of the first blasting caps in 1867 [7], is the first primary explosive to see practical application. The high costs associated with mercury, the high sensitivity of mercury fulminate, and its ability to lose performance under high loading pressures paved the way for lead azide (2) to replace the compound starting in the early 1900s [8]. Today, lead azide (including its less sensitive dextrin-coated form) finds wide-ranging application in energetic materials as the main primary explosive ingredient in blasting caps and detonators.…”

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.

“…N-heterocycles with sulfhydryl ligands are capable of -N(H)-C(=S) $ -N=C(-SH) tautomerization. Heterocyclic nitrogen can participate in coordination, while the sulfhydryl moiety can be used as a bridging group [8][9][10][11][12][13][14]. The soft sulfhydryl group has good coordination ability, because it has empty 3d orbital that can accept electrons from the metal [8,[14][15][16].…”
