Electrochemistry of Room Temperature Protic Ionic Liquids
The Journal of Physical Chemistry B, 2008Eighteen protic ionic liquids containing different combinations of cations and anions, hydrophobicity, viscosity, and conductivity have been synthesized and their physicochemical properties determined. In one series, the diethanolammonium cations were combined with acetate, formate, hydrogen sulfate, chloride, sulfamate, and mesylate anions.

Liquid chromatography with room temperature ionic liquids
JPC - Journal of Planar Chromatography - Modern TLC, 2017Room temperature ionic liquids are a new class of solvents of potential interest for liquid chromatography. Ionic liquids possess a combination of physical and solvation properties that are complementary to conventional organic solvents. Applications in liquid chromatography are currently limited by their unfavorable viscosity and low-wavelength ...

Determination of an Acidic Scale in Room Temperature Ionic Liquids
Journal of the American Chemical Society, 2003The acidity scale of different Brønsted acids in ionic liquids such as [BMIM][NTf2], [BMIM][BF4], and [BMMIM][BF4] has been investigated by determination of Hammett functions, using a spectrophotometric indicator method. This scale should permit one to correlate the acidity strength of ionic liquid systems with their ability to achieve acid-catalyzed ...

Ethenolysis of Methyl Oleate in Room‐Temperature Ionic Liquids
ChemSusChem, 2008AbstractUnsaturated vegetable oils are an attractive renewable feedstock, and the selective cleavage of unsaturated fatty esters is an important transformation in this respect. The efficient and selective cross‐metathesis of methyl oleate with ethylene was achieved under mild conditions with ruthenium‐alkylidene catalysts in toluene and room ...

Heterogeneous Solute Dynamics in Room-Temperature Ionic Liquids
The Journal of Physical Chemistry B, 2007The excitation wavelength dependence of the emission kinetics of several solutes is used to demonstrate the presence of dynamic heterogeneity in two representative room temperature ionic liquids, dimethyl-isopropyl-propyl-ammonium bis(trifluoromethylsulfonyl)imide [N(ip311)(+)][Tf(2)N(-)] and N-propyl-N-methylpyrrolidinium bis(trifluoromethylsulfonyl ...

Discovery of Room Temperature Ionic Liquid
Resonance, 2021[EtNH3]+(NG 3 − ) is generally considered as the first reported room temperature ionic liquid which was synthesized and characterized by Paul Walden in 1914. But the present investigation finds that [EtNH3]+(NG 3 − ), a similar kind of ionic salt which is liquid

Ionic Diffusion and Dissociation in Room-Temperature Ionic Liquids
Key Engineering Materials, 2020The clarification of the degree of ionic dissociation occurring in liquid-electrolyte systems such as those used in current lithium-ion batteries is important from both, fundamental and application points of views. In the present study, based on the bond strength–coordination number fluctuation (BSCNF) model proposed by the authors, we consider the ...
