Local structures of water in 1-butyl-3-methylimidazolium tetrafluoroborate probed by high-pressure infrared spectroscopy.
We have investigated the aggregation behaviors of water molecules in 1-butyl-3-methylimidazolium tetrafluoroborate/water mixtures using high-pressure methods. Under ambient pressure, the IR spectra indicate that two types of O-H species: free O-H and bonded O-H, existing in ionic liquid/water mixtures. As samples were compressed, a continuous loss of the free O-H band intensity was observed. Th...
متن کاملThermodynamic Study of the Ternary Electrolyte (1-Butyl-3-methylimidazolium chloride + sodium chloride + Water) System Using Potentiometric Measurements
In this paper, the thermodynamic properties of the aqueous mixed electrolyte system containing 1-butyl-3-methylimidazolium chloride ([BMIm]Cl) and NaCl are reported based on the potentiometric method. The potentiometric measurements were performed on the galvanic cells without liquid junction of the type:Ag-AgCl [BMIm]Cl (m1), NaCl(m2), H2O│IL-...
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 کامل1-Butyl-3-Methylimidazolium Bromide Promoted Selectively Oxidation of Sulfur Compounds by NaBrO3
1-Butyl-3-methylimidazolium bromide ([bmim]Br) as an ionic liquid promoted selectively oxidation of aliphatic and aromatic sulfides to the corresponding sulfoxides and the oxidative coupling of thiols to disulfides by NaBrO3 in excellent yields under neutral conditions.
متن کاملInfluence of Ionic Liquid 1- butyl-3-methylimidazolium Chloride on the Soil Micro-Ecological System
In order to evaluate the influence of ionic liquid 1butyl-3-methylimidazolium chloride ([Bmim]Cl) on the soil micro-ecological system, the toxicity of [Bmim]Cl to soil microorganisms and its impact on soil physico-chemical properties were investigated. Three soil samples, which were taken from the rape land, nursery land and the broad bean land respectively, were used for this study. The toxici...
