Densities, ρ 123 , and speeds of sound, u 123 , of 1-ethyl-3-methylimidazolium tetrafluoroborate (1) + 2-methylaniline (2) + pyridine or α-, β-, or γ-picoline (3) ternary mixtures have been measured over the entire range of composition at 293.15 K, 298.15 K, 303.15 K, and 308.15 K using density and speed of sound analyzer (Anton Paar DSA 5000). The heat capacity, C p , of pure liquids pyridine and α-, β-, and γ-picoline have also been measured at 293.15 K, 298.15 K, 303.15 K, and 308.15 K using differential scanning calorimeter. The measured data have been employed to determine excess molar volumes, V 123 E and excess isentropic compressibilities,(κ S E ) 123 . The V 123 E and(κ S E ) 123 data have been fitted to Redlich−Kister equation to calculate ternary adjustable parameters and standard deviations. The thermodynamic properties of the ternary mixtures have been analyzed in terms of Graph (which deals with the topology of the constituent of mixtures) and Prigogine-Flory-Patterson (PFP) theories. It has been observed that Graph theory describes well V 123 E and (κ S E ) 123 data of the studied ternary ionic liquid mixtures. However, PFP theory correctly predicts the sign of V 123 E and (κ S E ) 123 data of the studied mixtures.

“…THP, 1-pentanol were purchased from Aldrich chemical Company with purities >0.998, the purities of the purified liquids were checked by measuring their sound velocity, densities [recorded in Table 1] using Anton Paar DSA 5000M at the range of 298.15 to 318.15 K (± 0.01 K) and these agreed to within ±2 × 10 −3 kg m −3 with their literature values [11][12][13][14][15][16][17][18][19][20]. Sound velocity (u), densities (ρ) of the pure liquids and their binary mixture were measured using a vibrating U-tube digital density and sound analyzer as explained in the literature [21,22] which is the same as claimed by the manufacturer.…”

Sound velocity, densities of binary mixture of Tetrahydropyran (THP) with 1-hexanol has been measured over the entire range of composition at T = 298.15 to 318.15 K. The excess parameters viz., excess sound velocity, deviations in isentropic compressibility, excess molar volume, excess free length and excess acoustic impedance are deduced from experimental values and discussed intermolecular interactions present in the mixture. At the end all the parameters have been fitted to Redlich-Kister equation and their coefficients are obtained.

“…[13,14]. The densities, q and speeds of sound, u values of the purified liquids (measured by using a density and sound analyzer, Anton Paar DSA 5000) are listed in Table 1 [13][14][15][16][17][18][19][20][21][22][23][24]. The density and speed of sound values of the pure liquids were measured in the manner as described elsewhere [25,26].…”

The excess molar heat capacities, C E P À Á 12 , of binary mixtures of o-chlorotoluene (1) with pyridine, a-, b-or c-picoline, benzene, toluene or o-xylene (2) have been measured as a function of composition at 298.15, 303.15 and 308.15 K using a micro differential scanning calorimeter (Model-lDSC 7 Evo). The C E P À Á 12 data have been fitted with the Redlich-Kister equation to calculate binary adjustable parameters along with standard deviations. The sign and magnitude of values of o-chlorotoluene (1) ? pyridine or a-or b-picoline (2) are dictated by the relative proportion of components in the mixtures. However C E P À Á 12 values for o-chlorotoluene (1) ? c-picoline (2) mixture are positive and C E P À Á 12 values for o-chlorotoluene (1) ? benzene or toluene or o-xylene (2) mixtures are negative over the entire mole fraction range. The topology of the constituent molecules has been employed (Graph theory) to determine the C E P À Á 12 data of the studied mixtures. It has been observed that C E P À Á 12 values obtained by Graph theory are in agreement with the experimental values.
