“…A review of the literature revealed that thermodynamic properties of ternary mixtures containing the IL [EMIM][BF 4 ] with various organic solvents have been explored at varying temperatures by a number of researchers. − There have been no data published on the thermodynamic properties of the currently explored ternary mixtures. As a result, the originality of the current study is emphasized.…”

Volumetric and acoustic properties were obtained using density, ρ 123 , and speed of sound, u 123 , experimental values for ternary systems of {[EMIM][BF 4 ] (x 1 ) + acetic acid (x 2 ) + acetophenone (x 3 )} (mix 1 ) and {[EMIM][BF 4 ] (x 1 ) + propionic acid (x 2 ) + acetophenone (x 3 )} (mix 2 ) at T = (293.15−333.15) K and 0.1 MPa. The observed V m123 Eand Δk s123 data of the studied ternary mixtures were modeled with a total of 63 evaluated models, which resulted from a sum of each of nine predictive terms (no estimated parameters) with each of seven correlative terms (estimated parameters). The entire model is a correlative model, and if all of the parameters of the correlative term are set to zero, it becomes a predictive model. The ideal number of parameters in the correlation was then approximated using standard deviations (σ). For mix 1 , V m123 E was only negative and Δk s123 was only positive, while for mix 2 both negative and positive results were found for each property. Also, quantitative results point out that mix 1 is closer to ideal behavior than mix 2 . The modeling for mix 2 employed more complex equations, with more parameters, and even so presented worse deviations than for mix 1 . These results evidence the effect of one CH 2 in the acid chain on the thermodynamic properties of these mixtures.

In the present work, we obtained density (ρ 123 ), speed of sound (u 123 ), excess molar volume (V m123 E ), and deviation in isentropic compressibility (Δk s123 ) for ternary mixtures of {[BMIM][BF 4 ] (x 1 ) + acetic acid (x 2 ) + acetophenone (x 3 )} (mixture 1), {[BMIM][BF 4 ] (x 1 ) + propionic acid (x 2 ) + acetophenone (x 3 )} (mixture 2), and {[BMIM][PF 6 ] (x 1 ) + acetic acid (x 2 ) + acetophenone (x 3 )} (mixture 3) at temperatures ranging between 293.15 and 333.15 K and at a pressure of 0.1 MPa. V m123 Eand Δk s123 values of the ternary systems were modeled with 9 predictive (no estimated parameter) and 7 correlative terms, leading to a total of 63 evaluated models. Using a standardized deviation (σ), it was possible to estimate the optimal number of parameters in the correlation, which varied from 1 to 11. The average σ for V m123 E mixture 3 was about twice the values for mixtures 1 and 2, even using more parameters for the last mixtures. For Δk s123 , σ is in the same range for the three mixtures, even though only one parameter is used in each temperature for mixture 1 and up to 11 are used in mixtures 2 and 3. These results indicate that nonideality qualitatively is in the order mixture 3 > mixture 2 > mixture 1.
