In order to obtain the regularities of physicochemical properties of hydroxy protic ionic liquids (PILs) and broaden their potential application, a series of 2-hydroxyethylammonium sulfonate-based PILs were synthesized through proton transfer reaction and characterized by NMR and FT-IR and elemental analysis. Their phase transfer behavior ( T m ) and initial decomposition point ( T d ) were characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), respectively. Meanwhile, the regularities of density (ρ), viscosity (η) and electrical conductivity (σ) of synthesized PILs at different temperatures were measured. The results indicated that their physicochemical properties were tightly related with their structures and the interactions between cations and anions. In addition, the dissociation constants (p K a) of synthesized PILs were obtained by acid-base titration, which revealed that all synthesized PILs had p K a exceeding 7 and their cations were the crux of determining the p K a value. Moreover, several synthesized PILs with a low melting temperature also showed potential application in the deoxidation reaction of cyclohexanol, as they had conversion rates approximating 100% and the selectivity of cyclohexane or cyclohexene was about 80%.

“…The alkyl groups in the diluent, n -dodecane or ionic liquid, also can give rise to bands in the same region. The NTf 2 − group of the ionic liquid gives a band in the range of 650 -660 cm −1 , which is attributed to the S-N-S bending mode [30] , while the S-N-S asymmetric stretching band comes around 1058 cm −1 [31] . The S-O stretch is expected at around 1150 cm −1 .…”

Density, speed of sound, and viscosity values were measured for different binary mixture concentrations of 1-butyl-3methylimidazolium bis(trifluoromethylsulfonyl)imide ([Bmim][NTf 2 ]) + N-methylaniline (NMA) and 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][Pf 6 ]) + NMA systems at temperatures from T = 298.15 to 323.15 K under atmospheric pressure. The excess values of molar volume, molar isentropic compressibility, intermolecular free length, and viscosity were calculated. The partial molar volumes and partial molar isentropic compressibilities at infinite dilutions were also estimated. The Redlich−Kister equation was utilized to evaluate coefficients and standard deviations. The mechanism of effective packing between [Bmim][NTf 2 ]/ [Bmim][Pf 6 ] and NMA was represented by the negative excess molar volumes. In both the studied systems, the occurrence of strong chemical interactions was represented by the negative excess intermolecular free length values. The present work clearly showed that the simultaneous analysis of excess properties could provide a comprehensive description of molecular interactions occurring in the binary mixtures, specifically if the component molecules have different sizes. Further, the high viscosities of the ionic liquids were decreased by mixing with low viscous NMA. Hence, the investigated systems could be more suitable for their possible applications in the transport mechanism and absorption of gasses.
