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 کاملTemperature dependence of the electrical conductivity of imidazolium ionic liquids.
The electrical conductivities of 1-alkyl-3-methylimidazolium tetrafluoroborate ionic liquids and of 1-hexyl-3-methylimidazolium ionic liquids with different anions were determined in the temperature range between 123 and 393 K on the basis of dielectric measurements in the frequency range from 1 to 10(7) Hz. Most of the ionic liquids form a glass and the conductivity values obey the Vogel-Fulch...
متن کامل6. Green chemistry: Ecotoxicity and biodegradability of ionic liquids
Green chemistry plays a very important role in the sustainable development, seeking to reduce and prevent pollution at its source, minimizing the hazard and maximizing the efficiency of the chemical processes. Ionic liquids (ILs) are a new generation of chemicals that have a great potential for contributing to the greenness of chemical processes and developing new applications, both being of in...
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...
