Phase behaviour and physico-chemical properties of the binary systems {1-ethyl-3-methylimidazolium thiocyanate, or 1-ethyl-3-methylimidazolium tosylate+water, or+an alcohol}

Influence of the anion on the surface tension of 1-ethyl-3-methylimidazolium-based ionic liquids

“…It should be stressed that the authors employed both the du Noüy ring and Wilhelmy plate methods to confirm the accuracy of the measurements [31,33]. Although some large deviations exist between our data and literature data it must be noted that large deviations are still observed among the data from differ- [28,34]. These differences could be attributed to the ionic liquid purity level, including the amount of water, halides, volatile compounds, and other surface-active contaminants such as oxygen-containing carbohydrates and polysiloxanes [36,37].…”

“…The percentage relative deviations (%RD) between our data and those from literature [28][29][30][31][32][33][34][35] are summarized in figure 3. Positive and negative relative deviations are found between our data and those already published.…”

“…Therefore, discrepancies inevitably exist among different authors. Among the ionic liquids here studied, surface tension data for [C 2 [34].…”

Eutectic mixtures of pyrrolidinium-based ionic liquids

“…[11][12][13] The solid-liquid phase behaviour for this kind of systems has been studied intensely. [14][15][16][17][18] Unfortunately the disadvantage of this approach is that such mixtures do not always preserve desired properties of ILs like e.g. non-volatility or aprotic character.…”

Physico-chemical properties and phase behaviour of piperidinium-based ionic liquids

“…Recently, the activity coefficients of many organic solvents and water were measured in [PMPIP][NTf 2 ] [26]. The selectivities obtained for the separation of the aromatic hydrocarbons from the aliphatic hydrocarbons were on the average level, but the selectivity for the n-hexane/thiophene separation problem was quite high, S ∞ 12 = 28.6 at T = 308.15 K. The choose of anions in this work was dictated by the previous very optimistic results in the extraction with the thiocyanate-based-anion ionic liquids [16,17,[27][28][29][30] and with the bis{(trifluoromethyl)sulfonyl}imide-based-anion ionic liquids [21][22][23][24][25]. This paper is a continuation of our wide ranging investigation into ILs containing the thiocyanate anion.…”
