A family of new nitrogen-rich energetic tetrazoles, di(1H-tetrazol-5-yl)methanone oxime and 5,5′-(hydrazonomethylene)bis(1H-tetrazole), was synthesized in very good yields from inexpensive starting materials. These tetrazoles have excellent thermal stabilities high nitrogen content as well acceptable impact friction sensitivities were employed precursors to salts. The hydrazinium hydroxyl ammonium salts 5,5′-(hydrazonomethylene)bis(1H-tetrazole) exhibit detonation velocities (9050 m s−1 8839...
Abstract Two series of boronium‐cation‐based ionic liquids were prepared and fully characterized by 1 H, 13 C, 11 B NMR infrared spectroscopy, differential scanning calorimetry (DSC), elemental analysis. The structure bis(1‐methyl‐1 H ‐imidazole‐3‐yl)dihydroboronium dicyanoborohydride ( 5 a ) was determined single‐crystal X‐ray diffraction. densities these range from 1.05 to 1.28 g cm −3 , the heats formation, predicted on basis Gaussian 03 calculations, fall between −164.6 430.5 kJ mol −1 ....
Abstract Hydrazine and its derivatives are used as fuels in rocket propellant systems; however, due to high vapor pressure, toxicity, carcinogenicity, handling of such compounds is extremely hazardous. Hypergolic ionic liquids have shown great promise become viable replacements for hydrazines fuels. Borohydride‐containing now been synthesized using a more efficient synthetic pathway that does not require liquid ammonia halide precursors. Among the eight new compounds,...
Nickel(<sc>ii</sc>), cobalt(<sc>ii</sc>) and manganese(<sc>ii</sc>) <italic>N</italic>-alkylimidazole bis[(trifluoromethyl)sulfonyl]imide magnetic ionic liquids were synthesized from their chloride intermediates physicochemical properties studied.
Direct quaternization of 1-methyl-1,2,4-triazole with n-alkyl methanesulfonates (alkyl = butyl, octyl, dodecyl) showed to be an atom-economic, convenient, mild, solvent- and halide-free way obtain 1,2,4-triazolium methanesulfonate ionic liquids in high purity yield. Subsequent metathesis lithium bis(trifluoromethanesulfonyl)amide (LiTf2N) allows for a much desired, easy access halide-free, liquids. Differential scanning calorimetry confirms that all investigated compounds qualify as (ILs)....
Abstract A new and simple method is developed to synthesize carbon microspheres decorated with iron sulfide nanoparticles for mercury ion removal from water. The synthesis based on carbonizing polystyrene–divinylbenzene-based iron(III) sulfate-loaded cation exchange resins between 500 1000 °C. phase composition, surface area, morphology of these materials are characterized by various spectroscopic diffraction techniques, including Mössbauer spectroscopy, powder X-ray diffraction, Raman...
The effect of chemical structure on various physiochemical properties including thermal stability, solvent miscibility, magnetic susceptibility and viscosity is studied for acetylacetone based ionic liquids.
