“…The effect of water on the properties of the [C 6 mim][NTf 2 ] was studied by Widegren and Magee [4] (densities, viscosities, speeds of sound, and electrolytic conductivities) and Widegren et al [37] (electrolytic conductivities). Figures 10-13 show the variation of these properties with water content, as reported by Widegren and Magee [4].…”

This article is a product of IUPAC Project 2002-005-1-100 (Thermodynamics of ionic liquids, ionic liquid mixtures, and the development of standardized systems). Experimental results of thermodynamic, transport, and phase equilibrium studies made on a reference sample of the ionic liquid 1-hexyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]amide are summarized, compared, and critically evaluated to provide recommended values with uncertainties for the properties measured. Properties measured included thermal properties (triple-point temperature, glass-transition temperature, enthalpy of fusion, heat capacities of condensed states), volumetric properties, speeds of sound, viscosities, electrolytic conductivities, relative permittivities, as well as properties for mixtures, such as gas solubilities (solubility pressures), solute activity coefficients at infinite dilution, and liquid-liquid equilibrium temperatures. Recommended values with uncertainties are provided for the properties studied experimentally. The effect of the presence of water on the property values is discussed.

“…Widegren et al [18] measured electrolytic conductivities from T = (288 to 323) K with a smallvolume commercial conductivity cell with a cell constant of (99.89 ± 0.7) m -1 . The measured resistance was extrapolated to f → ∞.…”

“…w(H 2 O) was 4.5ؒ10 -5 before and 1.65ؒ10 -4 after the measurements. Values of relative permittivity ε were obtained by fitting a Cole-Cole model for the dominant low-frequency process and a Debye model for the higher-frequency process [18]. The estimated uncertainty for ε is 1, which corresponds to relative uncertainties from (7 to 9) %.…”

This article summarizes the results of IUPAC Project 2002-005-1-100 (Thermodynamics of ionic liquids, ionic liquid mixtures, and the development of standardized systems). The methods used by the various contributors to measure the thermophysical and phase equilibrium properties of the reference sample of the ionic liquid 1-hexyl-3-methylimidazolium bis [(trifluoromethyl)sulfonyl]amide and its mixtures are summarized along with the uncertainties estimated by the contributors. Some results not previously published are presented. Properties of the pure ionic liquid included thermal properties (triple-point temperature, glass-transition temperature, enthalpy of fusion, heat capacities of condensed states), volumetric properties, speeds of sound, viscosities, electrolytic conductivities, and relative permittivities. Properties for mixtures included gas solubilities, solute activity coefficients at infinite dilution, liquid-liquid equilibrium temperatures, and excess volumes. The companion article (Part 2) provides a critical evaluation of the data and recommended values with estimated combined expanded uncertainties.

An overview of the field of ionic liquids is presented, including the nomenclature and types of ionic liquids. Their synthesis and purification methods are described, along with typical characterisation procedures and general physico‐chemical properties. The various applications of ionic liquids are also summarised including in batteries, in green chemistry as low vapour pressure solvents, in medicinal chemistry and in protein stabilisation.
