TLDR
The conductivities and viscosities of the room-temperature ionic liquid (IL) 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) + water + ethanol and [bmim] + water+ acetone ternary mixtures were determined in this paper.Abstract:
The conductivities and viscosities of the room-temperature ionic liquid (IL) 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) + water + ethanol and [bmim][PF6] + water + acetone ternary mixtures were determined in the temperature range from 288.15 K to 308.15 K, and the mole fraction of the solvents in the mixtures was up to 0.48. The conductivities of the mixtures increased with increasing concentration of the solvents and temperature in the solvent concentration range studied. An increase in temperature or solvent concentration results in reduction in the viscosities of the mixtures.read more

The peculiar effect of water on ionic liquids and deep eutectic solvents
TL;DR: In this review, published experimental and theoretical results for IL/DES-H2O systems at varied water concentrations are collected and analyzed and a new conceptual framework is suggested for thermodynamic modelling of IL/ DES- H2O binary systems to enable new technologies for their practical applications.

The effect of dissolved water on the viscosities of hydrophobic room-temperature ionic liquids
TL;DR: Data for viscosity vs. water content for three hydrophobic room-temperature ionic liquids show that their viscosities are strongly dependent on the amount of dissolved water.

Effect of water and organic solvents on the ionic dissociation of ionic liquids.
TL;DR: It can be deduced that the organic solvents enhance the ionic association of the ILs, the effect depending on the solvent dielectric constant, while water promotes dissociation significantly due to its high dielectrics constant and its ability to form strong hydrogen bonds with the anions of theILs.
