X‐ray Photoelectron Spectroscopy of Pyridinium‐Based Ionic Liquids: Comparison to Imidazolium‐ and Pyrrolidinium‐Based Analogues
We investigate eight 1-alkylpyridinium-based ionic liquids of the form [Cn Py][A] by using X-ray photoelectron spectroscopy (XPS). The electronic environment of each element of the ionic liquids is analyzed. In particular, a reliable fitting model is developed for the C 1s region that applies to each of the ionic liquids. This model allows the accurate charge correction of binding energies and ...
متن کاملDensities, Viscosities and Derived Thermophysical Properties of Water-Saturated Imidazolium-Based Ionic Liquids.
In order to evaluate the impact of the alkyl side chain length and symmetry of the cation on the thermophysical properties of water-saturated ionic liquids (ILs), densities and viscosities as a function of temperature were measured at atmospheric pressure and in the (298.15 to 363.15) K temperature range, for systems containing two series of bis(trifluoromethylsulfonyl)imide-based compounds: th...
متن کاملImidazolium-based Ionic liquids on Morphology and Optical Properties of ZnO Nanostructures
ZnO nanostructures have been synthesized by a simple reflux method, using different ionic liquids, such as 1-benzyl-3-methylimidazolium bromide ([BzMIM][Br]), 1,1'-(1,4 phenylenebis (methylene)) bis (3-methyl-1H-imidazol-3-ium) bromide ([MM-1,4-DBzIM2][Br]2) and 1-phenacyl-3-methylimidazolium bromide ([PMIM][Br]), with different amount of sodium hydroxide in water. Als...
متن کاملAntioxidative properties of pyrrolidinium and piperidinium salts.
Two series of pyrrolidinium (PYA-n) and piperidinium (PPPA-n) bromides with incorporated antioxidant function were synthesized. Both have hydrocarbon chains with odd number of the carbon atoms (n) ranging between 7 and 15. Pig erythrocytes (RBC) were used to study antioxidant activity of these compounds. They were incorporated into RBC membranes in sublytic (micromolar) concentrations and RBC w...
متن کاملSynthesis and Thermal Characterization of Mono and Dicationic Imidazolium Pyridinium Based Ionic Liquids
A series of monocationic and dicationic ionic liquids, in which each ionic liquid is associated with dicyanamide anion, are synthesized. The molecular structures of these compounds were identified by 1H-NMR, FT-IR and CHN analysis. Thermal behaviors of these ionic liquids were also investigated by thermogravimetry (TGA). The results suggested that all new ionic liquids have reasonable thermal s...
