Transport properties of binary mixtures of carbon dioxide and 1-butyl-3-methylimidazolium hexafluorophosphate studied by transient grating spectroscopy.
Transient grating spectroscopy was applied to measurements of sound velocity and thermal diffusivity in binary mixture solutions of carbon dioxide (CO(2)) and 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIm][PF(6)]) along the saturated line of CO(2) at 40 degrees C up to 20.0 MPa. The sound velocity decreased more than 10% by increasing the pressure to 10 MPa, and the pressure effect was...
متن کاملReduction of carbon dioxide in 1-butyl-3-methylimidazolium acetate.
Gaseous CO(2) is almost irreversibly absorbed by the room temperature ionic liquid 1-butyl-3-methylimidazolium acetate ([C(4)mim][Ac]) in which it undergoes a chemically irreversible, one electron electrochemical reduction, suggesting a means for the sequestration of the greenhouse gas.
متن کاملOn the spontaneous carboxylation of 1-butyl-3-methylimidazolium acetate by carbon dioxide.
The formation of 1-butyl-3-methylimidazolium-2-carboxylate in the mixture of CO(2) with 1-butyl-3-methylimidazolium acetate under mild conditions (298 K, 0.1 MPa) has been put in evidence in the liquid phase using Raman and infrared spectroscopy complemented by DFT calculations and NMR ((1)H, (13)C, (15)N) spectroscopy.
متن کاملCarbon dioxide in 1-butyl-3-methylimidazolium acetate. I. Unusual solubility investigated by Raman spectroscopy and DFT calculations.
The unusual solubility of carbon dioxide in 1-butyl-3-methylimidazolium acetate (Bmim Ac) has been studied by Raman spectroscopy and DFT calculations. It is shown that the solubility results from the existence of two distinct solvation regimes. In the first one (CO(2) mole fraction ≤ 0.35), the usual Fermi dyad is not observed, a fact never reported before for binary mixtures with organic liqui...
متن کاملUultra-trace determination of cadmium (II) in aqueous environmental samples by a new ion selective electrode based on nefazodone and 1-butyl-3-methylimidazolium hexafluorophosphate ionic liquid
Background and Objective: Cadmium is a potential environmental contaminant that causes adverse effects on the environment and the health of living organisms. Therefore, designing a simple and economic technique for its determination is very important. In this respect, a potentiometric sensor based on nefazodone as the ionophore and [BMIM]PF6 as the ionic additive were developed for the determin...
