Photo-degradation of Imidazolium Ionic Liquids
Degradation of imidazolium ionic liquid, [bmim][TFSA] and iodide solution of [bmim][TFSA] by UV-laser irradiation has been studied through ground state absorption and transient absorption spectroscopy. We found that excited state [bmim] undergoes degradation efficiently. Introduction Room-temperature ionic liquids are receiving considerable attention because of their remarkable properties, such...
متن کاملVibrational spectra of imidazolium tetrafluoroborate ionic liquids
The Raman and infrared spectra of a series of 1-alkyl-3-methylimidazolium tetrafluoroborate ionic liquids ([C2-4MIM][BF4]) are reported and analyzed using Density Functional Theory (DFT) and RHF methods at the 6-311+G(2d,p) computational level. The B3LYP (DFT) and RHF calculations reproduce the vibrational spectra of 1-ethyl-3-methyl imidazolium tetrafluoroborate [EMIM][BF4], 1-propyl-3-methyl ...
متن کاملAggregation of imidazolium ionic liquids in molecular liquids studied by small-angle neutron scattering and NMR.
The aggregation of two imidazolium-based ionic liquids, 1-ethly-3-methylimidazolium chloride (EMI(+)Cl(-)) and EMI(+) bis-(trifluoromethanesulfonyl)amide (EMI(+)TFSA(-)), in molecular liquids, water, methanol, acetonitrile, and benzene, has been studied by using the small-angle neutron scattering (SANS) technique. The SANS results have shown that the heterogeneity of EMI(+)Cl(-)-acetonitrile mi...
متن کاملSurfactant properties of ionic liquids containing short alkyl chain imidazolium cations and ibuprofenate anions.
Interfacial tension, electrical conductivity, NMR self-diffusion and DLS experiments have been used to investigate the self-aggregation in water of ionic liquids associating an ibuprofenate anion and 1-alkyl-3-methylimidazolium [C(n)MIm](+) (n = 4, 6, 8) cations. Despite the short alkyl chain on imidazolium cations (n ≤ 8), these ionic liquids exhibit particularly low Critical Aggregation Conce...
متن کاملMicellization of long-chain ionic liquids in deep eutectic solvents.
The aggregation behavior of the ionic liquid (IL) 1-alkyl-3-methylimidazolium chloride with different alkyl chain lengths in a deep eutectic solvent (DES, composed of choline chloride and glycerol in a 1 : 2 mole ratio) was studied for the first time. The critical micellar concentration, micellar size and intermolecular interactions in IL/DES solutions were investigated by different techniques ...
