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.

“…Zábranský et al [94] assigned uncertainty 0.3 % to the data covering temperature range from the normal melting point temperature 267.13 K [75] to 420 K (data are available up to 680 K, but these values are not relevant to this work). Although newer results are available [77], they differ from the data selected by Zábranský et al [94] by more than the assigned uncertainty (see Fig.5) and were not considered in the calculations. For nitromethane, Zábranský et al [95] selected the data by Jones and Giauque [31], Berman and West [78], and Cerdeiriña et al [79].…”

“…For the development of model/theories and also to obtain a better understanding for the use of ionic liquids as alternative to conventional organic solvents in chemical and separation processes, measurements of thermodynamic properties of liquid mixtures containing ionic liquids are required [4,6]. In earlier publication [7][8][9][10][11], excess molar volumes and excess isentropic compressibilities for binary and ternary mixtures containing 1-ethyl-3-methylimidazolium tetrafluoroborate as one of the component have been reported. No excess molar enthalpy data of 1-ethyl-3-methylimidazolium tetrafluoroborate (1) ?…”

Excess molar enthalpies, H E 123 of ternary 1-ethyl-3-methylimidazolium tetrafluoroborate (1) ? 2-methyl aniline (2) ? aniline or N-methyl aniline (3); 1-ethyl-3-methylimidazolium tetrafluoroborate (1) ? water (2) ? formamide or N,N-dimethyl formamide (3) and H E of 2-methyl aniline (1) ? aniline or N-methyl aniline (2); 1-ethyl-3-methylimidazolium tetrafluoroborate (1) ? formamide (2) mixtures, have been measured at 298.15 K. The excess molar enthalpies, H E 123 , are negative for 1-ethyl-3-methylimidazolium tetrafluoroborate (1) ? 2-methyl aniline (2) ? aniline or N-methyl aniline (3) mixtures and are positive for 1-ethyl-3-methylimidazolium tetrafluoroborate (1) ? water (2) ? formamide (3) mixture over entire composition of (1) and (2) components. However, the magnitude and sign of H E 123 value for 1-ethyl-3-methylimidazolium tetrafluoroborate (1) ? water (2) ? N,Ndimethyl formamide (3) mixture vary by the relative composition of the constituent molecules. The H E 123 and H E data have also been tested in terms of Graph and Prigogine-Flory-Patterson theories.
