Ionic liquids behave as dilute electrolyte solutions.
We combine direct surface force measurements with thermodynamic arguments to demonstrate that pure ionic liquids are expected to behave as dilute weak electrolyte solutions, with typical effective dissociated ion concentrations of less than 0.1% at room temperature. We performed equilibrium force-distance measurements across the common ionic liquid 1-butyl-3-methylimidazolium bis(trifluorometha...
متن کاملEfficient precipitation of dyes from dilute aqueous solutions of ionic liquids.
The addition of only approximately 1.7 wt% (approximately 0.06 M) ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate to aqueous solutions of six popular cationic dyes resulted in the precipitation of almost all of the dye from the solution.
متن کاملSonochemistry and sonoluminescence in ionic liquids, molten salts, and concentrated electrolyte solutions
Ionic liquids have favorable intrinsic properties that make them of interest as solvents for various chemical reactions. The same properties that make the liquids effective solvents also make them interesting liquids for studies involving sonochemistry, acoustic cavitation, and sonoluminescence. Recent interest in using ultrasound to accelerate chemical reactions conducted in ionic liquids nece...
متن کاملNear-Wall Molecular Ordering of Dilute Ionic Liquids
The interfacial behavior of ionic liquids promises tunable lubrication as well as playing an integral role in ion diffusion for electron transfer. Diluting the ionic liquids optimizes bulk parameters, such as electric conductivity, and one would expect dilution to disrupt the near-wall molecular ordering. We study this ordering in the ionic liquids [Emim]+[NTf2]-, [Emim]+[DCA]-, and [C4mpyr]+[N...
متن کاملIonic Liquids as Grease Base Liquids
The rheological characteristics of one mineral oil and two ionic liquid (IL) based lubricating greases were explored as a function of thickener concentration. The ILs used are 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([BMIM][TFSI]) and trihexyltetradecylphosphonium bis(trifluoromethylsulfonyl)imide ([P6,6,6,14][TFSI]), with polytetrafluoroethylene (PTFE) particles used as t...
