Speed of sound in ionic liquids with a common ion as a function of pressure and temperature

Density, Viscosity, and Speed of Sound of Pure and Binary Mixtures of Ionic Liquids Based on Sulfonium and Imidazolium Cations and Bis(trifluoromethylsulfonyl)imide Anion with 1-Propanol

“…Table shows the densities for pure ILs and 1-propanol. For [Et 3 S]­[TFSI] it is possible to compare our measurements with data reported by Lee et al at 298.15 K, Bhattacharjee et al from (283.15 to 343.15) K, Nazet et al from (278.15 to 338.15) K and Yebra et al from (283.15 to 343.15) K. The AAPE is (2.015, 0.150, 0.014, and 0.043) %, respectively. For [Amim]­[TFSI] ionic liquid we compare our results with those from Wlazlo et al The AAPE is 0.206%.…”

“…The AAPE values from Pereiro et al, Geppert et al, and González et al are (0.0379, 0.0527, and 0.0048)%, respectively. For [Et 3 S]­[TFSI] ionic liquid we compare our speed of sound results with those from Yebra et al at temperatures from (283.15 to 343.15) K. Our values agree within an AAPE of 0.392%. ILs show mostly moderate or high absorption due to the velocity dispersion particularly at lower temperatures, according to Dzida et al They mentioned that large deviations from the linearity of the temperature dependence of the speed of sound can be used as an indirect proof of the existence of velocity dispersion.…”

“…The densities of the pure components were measured at atmospheric pressure in the temperature range (293.15 to 323.15) K, and results are given in Table . Figure presents the percentage deviations between obtained density values from this work for the pure [bmpyrr]­[NTf 2 ], Figure a and DEC, Figure b and those reported previously in the literature. ,,,− …”
