“…Isentropic compressibility of pure ILs at atmospheric pressure and at a given temperature or as a function of temperature, is request to gain a better understanding of inter-and intramolecular interactions including ions and substituent effects as well as for better and selective use in various chemical and industrial processes.

A complete review of the literature data on the speed of sound and ultrasound absorption in pure ionic liquids (ILs) is presented. Apart of the analysis of data published to date, the significance of the speed of sound in ILs is regarded. An analysis of experimental methods described in the literature to determine the speed of sound in ILs as a function of temperature and pressure is reported, and the relevance of ultrasound absorption in acoustic investigations is discussed. Careful attention was paid to highlight possible artifacts, and side phenomena related to the absorption and relaxation present in such measurements. Then, an overview of existing data is depicted to describe the temperature and pressure dependences on the speed of sound in ILs, as well as the impact of impurities in ILs on this property. A relation between ions structure and speeds of sound is presented by highlighting existing correlation and evaluative methods described in the literature. Importantly, a critical analysis of speeds of sound in ILs vs those in classical molecular solvents is presented to compare these two classes of compounds. The last part presents the importance of acoustic investigations for chemical engineering design and possible industrial applications of ILs.

Densities, viscosities, and electrical conductivities were determined and discussed for a binary mixture containing 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ionic liquid, [bmpyrr][NTf2], and diethyl carbonate (DEC) as a function of temperature (T = 293.15–323.15 K) at atmospheric pressure (p = 0.1 MPa) over the entire range composition. Based on experimental density data, the related excess molar volumes were calculated and fitted using Redlich–Kister’s polynomial equation. The Casteel–Amis equation was used to correlate data obtained from electrical conductivity measurements. The effect of viscosity on electrical conductivity was discussed by the Walden rule. The Bahe–Varela theory, derived from the the pseudo-lattice model, has been successfully applied to explain the influence of the mixture composition on electrical conductivity. Based on physicochemical characterization supported with computational simulations for binary mixtures ([bmpyrr][NTf2] + DEC), the interactions between these components were discussed.

“…The available studies on ILs+MSs have considered several types of prototypical MSs such as acetone [36], acetonitrile [37] or dimethyl sulfoxide [38]. Regarding possible MSs for developing ILs+MSs mixtures, 1-alkanol is of great relevance as well [39,40]. The study of self-association in 1-alkanols by hydrogen bonding (homoassociation), the development of ion-alkanol hydrogen bonding (heteroassociation) and its effect on anion-cation interactions (hydrogen bonding and coulombic forces) and on ion-clustering, and the evolution the evolution of all these forces upon mixing with ILs in the full composition range leads to pivotal information on the evolution of different types of hydrogen bonding upon mixing [19].…”

The characteristics of intermolecular forces in 1-butyl-3-methylimidazolium Bis(trifluoromethylsulfonyl)imide + ethanol mixtures were studied in the full composition range using a combined experimental and theoretical approach. Molecular clusters were used to model the short-range interactions between the ionic liquid and the primary alcohol, studied using density functional theory calculations, inferring preferred interaction sites, strength of interactions and topological characteristics of intermolecular forces. Dynamic viscosity and refraction index were measured as a function of mixture composition and temperature and analysed in terms of evolution of intermolecular forces. Raman IR studies were carried out and the analysis of selected spectral regions allowed to characterize hydrogen bonding evolution for all the possible interacting sites. Highlights Imidazolium ionic liquids.  Mixtures.  Experimental and theoretical study.  Intermolecular forces.  Hydrogen bonding.
