Ionic liquids (ILs), an alternative to conventional mol. organic solvents, have attracted the attention of the scientific community because of their tunable unique physicochem. properties. Among the tested strategies, addition of co-solvents is the most convenient choice to alter the physicochem. properties of ILs for their industrial applications. In the present article, we have measured the d. (ρ), speeds of sound (u), and refractive index (nD) for six binary mixtures of N-methylaniline (NMA) and N-ethylaniline (NEA) + BmimBF4 + HmimBF4 + OmimBF4 over the entire range of composition and at temperatures ranging from 293.15 to 323.15 K at 5 K intervals and at atm. pressure. Excess molar volume (VmE), excess molar isentropic compressibility (Ks,mE), and deviation in the refractive index (ΔφnD) on volume fraction basis were calculated from these measured thermophys. properties. Influence of temperature on the excess and deviation properties has been studied. VmE, Ks,mE, and ΔφnD were fitted to the Redlich-Kister polynomial equation, and the parameters for the binary coefficients are reported. The influence of the alkyl chain length of ILs on the thermophys. properties of the mixtures of secondary amines was studied. We have discussed the intermol. interactions between the ILs and amine mols. using well-known arguments. We further predicted the refractive indexes of the studied mixtures using various mixing rules, and the resulting values have been compared with the exptl. values through the standard deviation. Exptl. calculated excess molar volumes have been compared with the predicted values of the Prigogine-Flory-Patterson theory and the extended real association model at 298.15 K. In the experiment, the researchers used many compounds, for example, 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6Synthetic Route of C8H15BF4N2)
3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6) is a member of lonic liquids. A multidisciplinary study on lonic liquids is emerging, including chemistry, materials science, chemical engineering, and environmental science. More specifically, some important fundamental viewpoints are now different from the original concepts, as insights into the nature of lonic liquids become deeper. For example, the physicochemical properties of lonic liquids are now recognized as ranging broadly from the oft quoted “nonvolatile, non-flammable, and air and water stable” to those that are distinctly volatile, flammable, and unstable.
