“…This work is a continuation of our previous works − on thermodynamic properties of binary mixtures of imidazolium-based ILs with polar solvents. In the present study, we extend our investigation to ternary mixtures and report densities (ρ 123 ), speeds of sound ( u 123 ), excess molar volume ( V m 123 E ), and deviation isentropic compressibility (Δ k s 123 ) of {[BMIM][BF 4 ] ( x 1 ) + acetic acid ( x 2 ) + acetophenone ( x 3 )}, {[BMIM][BF 4 ] ( x 1 ) + propionic acid ( x 2 ) + acetophenone ( x 3 )}, and {[BMIM][PF 6 ] ( x 1 ) + acetic acid ( x 2 ) + acetophenone ( x 3 )} over the entire composition range at T = 293.15, 303.15, 313.15, 323.15, and 333.15 K and under atmospheric pressure.…”

“…The purity of acetophenone was verified by comparing our experimental ρ 123 and u 123 data with previous publications, − and the results are given in Table . In our previous publications, , we have carried out a comparison study between experimental densities and speed of sounds of studied ILs and carboxylic acids; hence, they are not repeated here. From Table , it can be observed that ρ and u values show a small deviation that falls within the experimental error.…”

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.

“…In our previous work, ,, we investigated V m123 E and Δ k s 123 properties of the corresponding binary mixtures of the current studied ternary mixtures. When compared with the binary mixtures, it was found that acetophenone + carboxylic acid mixtures have extreme V m123 E values from −0.6 cm 3 ·mol –1 (293 K) to −1.1 cm 3 ·mol –1 (333 K), while they range from −1.0 cm 3 ·mol –1 (293 K) to −1.6 cm 3 ·mol –1 (333 K) for [EMIM][BF 4 ] + acetic acid mixtures and from 2.6 cm 3 ·mol –1 (293 K) to −3.4 cm 3 ·mol –1 (333 K) for [EMIM][BF 4 ] + propionic acid mixtures and are mainly positive up to 5 cm 3 ·mol –1 for [EMIM][BF 4 ] + acetophenone.…”

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.
