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 کاملTolerance of Immobilized Yeast Cells in Imidazolium-Based Ionic Liquids
Ionic liquids (ILs) are considered as another ’green solvent’, after the supercritical carbon dioxide. They are a promising reaction medium for biocatalysis process. The tolerance of active cells in hydrophobic imidazolium-based ILs (1-R-3-methylimidazolium hexafluorophosphate, [RMim][PF6]) has been studied in this work. Calcium-alginate-entrapped baker’s yeast has been chosen as the model of l...
متن کامل1-Methylimidazole stabilization of gold nanoparticles in imidazolium ionic liquids.
Low levels of 1-methylimidazole additives have been found to have dramatic effects on the resulting stability of gold and bimetallic nanoparticles in ionic liquids (ILs).
متن کاملDirect electrochemical reduction of hemin in imidazolium-based ionic liquids
The direct electrochemical reduction of hemin, protoporphyrin(IX) iron(III) chloride, ligated with strong or weak heterocyclic bases, was investigated in the ionic liquids (IL), 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) and 1-octyl-3methylimidazolium hexafluorophosphate ([omim][PF6]), using cyclic voltammetry and chronocoulometry. Hemin complexed with N-methylimidazole (NMI)...
