Opis:
1,1-Dimethylbiguanidium 1H,1′H-5,5′-bistetrazole-1,1′-diolate (MGBTO), a novel nitrogen-rich energetic salt, was synthesized by cation exchange. Its structure was characterized by elemental analysis, FTIR, NMR, DTA and TG-DTG. Single crystal X-ray diffraction analysis revealed that MGBTO was crystallized in the monoclinic space group C2/c. Thermal analysis demonstrated that its thermal stability extended up to 531.1 K. The nonisothermal kinetic and apparent thermodynamic parameters of the exothermic decomposition of MGBTO were determined by the Kissinger and Ozawa methods. Its detonation velocity and detonation pressure were calculated on the basis of the Kamlet-Jacobs equation and were 6342 m·s–1 and 15.78 GPa, respectively. The impact and friction sensitivities of MGBTO were quantified using standard BAM (10 kg drop hammer) procedures. The results revealed that the salt has good mechanical sensitivity (FS > 120 N, IS > 40 J), thus indicating its potential applications as an energetic material.

Opis:
A nitrogen-rich, polynitro energetic compound with an N,N-azo linkage, 1,1’-azobis(3,5-dinitropyrazole) (ABDNP), has been synthesized by an oxidative coupling reaction of 1-amino-3,5-dinitropyrazole with different oxidizing agents. The target compound was characterized by IR spectroscopy, 1H and 13C nuclear magnetic resonance spectroscopy, elemental analysis, mass spectra, X-ray diffraction and differential scanning calorimetry (DSC). The DSC results show that 1,1’-azobis(3,5-dinitropyrazole) decomposes at a relatively high onset temperature (202.9 °C), which indicates that 1,1’-azobis(3,5-dinitropyrazole) has acceptable thermal stability. The energetic properties were obtained, with a measured density and heat of formation matched by theoretically computed values based on the B3LYP method.

Opis:
A non-aqueous titration method was developed to assay the insensitive high explosive 1,1-diamino-2, 2-dinitroethene (FOX-7). The weak acidic nature of FOX-7 (pKa 10.6) was exploited in the assay method. The sample was dissolved in the protophilic solvent N, N-dimethylformamide and titrated against sodium methoxide solution in benzene/methanol using azo violet as indicator. FOX-7 samples obtained from regular batch operations were assayed by this method and the results were compared with that of a recrystallized sample. The method is simple, rapid and has good accuracy and precision.

Opis:
A review of the available literature on the properties of 1,1-diamino-2,2dinitroethene (DADNE, FOX-7) and formulations containing FOX-7 is presented in this paper. The structural, thermal and spectroscopic properties as well as the sensitivity and explosive properties of FOX-7 are described. Compositions containing FOX-7 are characterized in details and their sensitivity and explosive properties are presented. Potential areas of application for such formulations have been identified.

Opis:
The influence of the reaction conditions on 4,10-dinitro-2,6,8,12-tetraoxa- 4,10-diazatetracyclo[5.5.0.05,903,11]dodecane (TEX) yield was studied. TEX was prepared by the reaction of 1,4-diformyl-2,3,5,6-tetrahydroxypiperazine with glyoxal in nitric acid. The influence of the acidity of reaction mixture and ratios of starting materials on the yield of TEX was examined and synthesis was optimised. The highest yield (37%) was obtained at 1,4-diformyl-2,3,5,6-tetrahydroxypiperazine/nitric acid molar ratio 67 and sulfuric acid/nitric acid molar ratio around 0.15. Starting material 1,4-diformyl-2,3,5,6-tetrahydroxypiperazine was prepared from formamide and glyoxal using triethylamine or other tertiary amines to adjust suitable basicity. The best yield (84%) of 1,4-diformyl-2,3,5,6-tetrahydroxypiperazine was reached at molar ratio triethylamine/formamide equal to 0.1.
