Ion−Ion Interactions and Conduction Mechanism of Highly Conductive Fluorohydrogenate Ionic Liquids

Characterization and Conduction Mechanism of Highly Conductive Vanadate Glass

This paper reviews recent studies of highly conductive barium iron vanadate glass with a composition of 20 BaO ∙ 10 Fe2O3 ∙ 70 V2O5 (in mol %). Isothermal annealing of the vanadate glass for several ten minutes at a given temperature, higher than glass transition temperature or crystallization temperature, caused an increase in σ. Substitution of CuI (3d10), ZnII (3d10) and CuII (3d9) for FeIII...

Interactions between Organic Compounds and Ionic Liquids. Selectivity and Capacity Characteristics of Ionic Liquids

Interactions and dynamics in ionic liquids.

Precise dielectric spectra have been determined at 25 degrees C over the exceptionally broad frequency range of 0.1 <or= nu/GHz <or= 3000 for the imidazolium-based room-temperature ionic liquids (RTILs) [bmim][BF4], [bmim][PF6], [bmim][DCA], and [hmim][BF4]. The spectra are dominated by a low-frequency process at approximately 1 GHz with a broad relaxation time distribution of the Cole-Davidson...

One-pot synthesis of highly regioselective β-azido alcohols catalyzed by Brønsted acidic ionic liquids

In this protocol, 3-(2-carboxybenzoyl)-1-methyl-1H-imidazol-3-ium chloride [Cbmim]Cl and sulfonic acid functionalized pyridinium chloride [pyridine-SO3H]Cl as a new, reusable, and green Brønsted acidic ionic liquid (BAIL) catalyst were synthesized and successfully used for the one-pot ring opening of epoxide with sodium azide (NaN3) in water at room temperature. Epoxides under ring-opening easi...

Trace of the thermally induced evolution mechanism of interactions between water and ionic liquids.

The thermally induced evolution mechanisms of various interactions in ionic liquids (1-butyl-3-methylimidazolium tetrafluoroborate, bmimBF(4)) and water mixtures have been investigated in this paper. In the near-infrared (NIR) spectroscopy, we focus mainly on nu(OH) and nu(CH) overtone regions. During heating of bmimBF(4) and water mixtures, the nu(OH) overtone peak shows a significant blue shi...
