Synthesis, characterization and properties of a new energetic salt 2,4-diamino-6-methyl-1,3,5-triazine dinitramide

A new nitrogen-rich energetic salt, 2,4-diamino-6-methyl-1,3,5-triazine dinitramide, was synthesized by combining silver dinitramide and 2,4-diamino-6-methyl-1,3,5-triazine perchlorate. The structure of this new energetic salt was confirmed using single-crystal X-ray diffraction, elemental analysis, Fourier transform infrared spectrometry, ultraviolet–visible spectrophotometry, and nuclear magnetic resonance spectroscopy. The thermal stability was determined using differential scanning calorimetry, differential thermal analysis, and thermogravimetric tandem infrared spectrometry. Results showed that the target compound exhibits good thermal decomposition resistance of up to 470 K and has 59.1% mass loss with Ea = 118.2 kJ mol?1. Additionally, the detonation pressure and velocity obtained using Kamlet-Jacobs equations are 23 GPa and 8.2 km s?1, respectively. Sensitivity test was also attempted. The impact sensitivity of this new energetic salt is 11.5 J, which is superior to that of RDX (7.4 J).

Synthesis and Characterization of a New Energetic Salt based on Dinitramide

The development of new ionic salt as green propellants is one of intense investigations to replace toxic N, N′-dimethylhydrazine. A new energetic salt N, N′,N′′-tri(propan-2-ylidene)methanetriamium dinitramide (NTAGDN) based on dinitramide was synthesized by reacting silver dinitramide with triaminoguanidinium chloride. The structure of this new energetic salt was confirmed by single-crystal X-ray diffraction, elemental analysis, Fourier transform infrared spectrometry, ultraviolet-visible spectrophotometry, and nuclear magnetic resonance spectroscopy. NTAGDN crystallizes in the orthorhombic space group R3ˉ. Thermal decomposition was studied by differential scanning calorimetry, differential thermal analysis, and thermogravimetric tandem infrared spectrometry. Results indicated that NTAGDN exhibited excellent resistance to thermal decompositions of up to 470 K and incurred an 80.54 % mass loss between 450 and 523 K via exothermic decomposition. The kinetic parameters of NTAGDN thermal decomposition were also obtained from the differential thermal analysis data by Kissinger's method with Ea = 125.46 kJ·mol-1. Moreover, based on the Kamlet-Jacobs formula, the detonation velocity and detonation pressure of NTAGDN were calculated as 6.3 km·s-1 and 15 GPa, respectively.

Detection of elastic and electric conductivity anomalies in Potassium Sulphamate single crystal

Elastic anomalies in Potassium Sulphamate, (KNH2SO3), above room temperature were detected from temperature variation of elastic constants measured by ultrasonic Pulse Echo Overlap technique. Potassium Sulphamate has been reported to be a ferroelectric and piezo electric material. The elastic constants C11, C44, C55 and C66 have exhibited weak anomalies around 350 K. The DC conductivity measurement along a, b, and c axes also supports this conclusion.
