“…In other words, according to eq , the speed of sound correlation approach developed by Gardas and Coutinho could be used to evaluate a priory the speed of sound of novel ILs in wide ranges of temperature at 0.1 MPa It is also very important to highlight that, to date, the group of Guan developed ionic parachors (see, for example, ref and references therein) which may then be used to refine the approach described by Gardas and Coutinho . Additionally, several novel models ,,− are also available in the literature to evaluate the volumetric properties of several ILs as a function of temperature and pressure. To sum up, using the various density models and ionic parachor available in the literature, such an approach may be refined to describe a better correlation of speed of sound of ILs.…”

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.
