SYNTHESIS OF DINITRAMIDE SALT 1-AMINO-1,2,3-TRIAZOLE

Показано, что динитразовая кислота легко взаимодействует с 1-амино-1,2,3-триазолом с количественным выходом образуя соответствующую высокоэнергетическую ионную соль. В ходе процесса солеобразования используется более безопасный и доступный растворитель, чем описано в литературе для ионных солей динитразота на основе различных триазолов. It was shown that dinitratic acid easily interacts with 1-amino-1,2,3-triazole in quantitative yield to form the corresponding high-energy ionic salt. During the salt formation process, a safer and more affordable solvent is used than described in the literature for dinitrazot ionic salts based on various triazoles.

New Photomagnetic Ionic Salts Based on [MoIV(CN)8]4− and [WIV(CN)8]4− Anions

Three new ionic salts containing [M(CN)8]4− (M = MoIV and WIV) were prepared using large complex cations based on a non-conventional motif built with the tris(2-aminoethyl)amine (noted hereafter tren) ligand, [{M’(tren)}3(μ-tren)]6+ (M’ = CuII and ZnII). The crystal structures of the three compounds show that the atomic arrangement is formed by relatively isolated anionic and cationic entities. The three compounds were irradiated with a blue light at low temperature, and show a significant photomagnetic effect. The remarkable properties of these compounds are (i) the long-lived photomagnetic metastable states for the [Mo(CN)8]4−-based compounds well above 200 K and (ii) the rare efficient photomagnetic properties of the [W(CN)8]4−-based compound. These photomagnetic properties are compared with the singlet-triplet conversion recently reported for the K4[Mo(CN)8]·2H2O compound.

Study on Physicochemical and Thermal Properties of Tetrabutylammonium-Based Cation Ionic Salts Induced by Al2O3 Additive for Thermal Energy Storage Application

The physicochemical and thermal properties of tetrabutylammonium bromide (TBA-Br) and tetrabutylammonium hexafluorophosphate (TBA-PF6), and their change with the addition of Al2O3, were investigated using infrared (IR) spectroscopy and by simultaneously conducting thermal thermogravimetric (TG) analysis and differential thermal analysis (DTA) to obtain the differential scanning calorimetry (DSC) thermogram. The change in the IR data is characterized by the growth of a large peak in the range of 3500 cm−1 and the reduction of peaks below 1000 cm−1 with the additive concentration. The decomposition temperature determined from the peak in the DTG curve is nearly constant for TBA-Br, and it decreases with the addition of Al2O3 for TBA-PF6, although it does not depend on the concentration of the additives. The DTA curve of ionic salts with the addition of Al2O3 shows additional peaks, which indicates a change in the sample’s temperature at disorder or phase transitions. The variation in the melting temperature with additive concentration is similar to that of decomposition temperature. The maximum heat of fusion value was approximately 67 kJ kg−1 for the doped TBA-Br and TBA-PF6 but was achieved at a different additive concentration. This is due to the additional disorder in the system induced by the dissolution of Al2O3.

Synthesis of energetic salts containing three heterocyclic anions by a one-pot condensation reaction

Energetic ionic salts 1 and 2 containing three heterocyclic anions were prepared in a one-pot reaction using 1,3,5-benzenetricarboxaldehyde, aminoguanidine salts, and organic energetic salts (5-nitrotetrazole and 3,5-dinitro-1,2,4-triazole ammonium salt).
