Ternary excess molar volumes of {methyltrioctylammonium bis(trifluoromethylsulfonyl)imide+ethanol+methyl acetate, or ethyl acetate} systems at T=(298.15, 303.15, and 313.15)K

Densities, speeds of sound, and refractive indices for binary mixtures of 1-butyl-3-methylimidazolium methyl sulphate ionic liquid with alcohols at T=(298.15, 303.15, 308.15, and 313.15)K

“…The Redlich-Kister smoothing equation was used to fit the derived properties and the Lorentz-Lorenz equation was used to correlate the excess molar volume and predict the density or refractive index of the binary systems. This work is a continuation of our previous investigations on the thermodynamic properties of ILs with organic solvents [8,11,[13][14][15][16][17][18][19][20]. To our best knowledge, there are no measurements of all three physical properties, i.e., density, speed of sound, or refractive index for the binary systems studied in this work at the four temperatures in the literature.…”

Influence of the alkyl group on thermophysical properties of carboxylic acids in 1-butyl-3-methylimidazolium thiocyanate ionic liquid at various temperatures

“…The open literature shows that there are no data currently available for the binary systems studied. The present work is a continuation of our systematic studies on thermodynamic and thermophysical properties of binary or ternary mixtures containing ILs [19][20][21][22][23][24][25][26][27][28][29][30]. The structure of the studied ionic liquid is given in figure 1.…”

Solubilities of Carbon Dioxide and Oxygen in the Ionic Liquids Methyl Trioctyl Ammonium Bis(trifluoromethylsulfonyl)imide, 1-Butyl-3-Methyl Imidazolium Bis(trifluoromethylsulfonyl)imide, and 1-Butyl-3-Methyl Imidazolium Methyl Sulfate

“…4 A relatively new type of solvent known as ionic liquids, has received much attention in recent years. Ionic liquids are molten salts that typically have melting points below 373.15 K. 8 The specific advantages of ionic liquids is that many can be tuned to have negligible vapour pressure, 9 good dissolution characteristics, 10 and are non-flammable 11 and non-toxic 12 , depending on the cation and anion used. It is for these reasons, that many ionic liquids have been regarded as -green‖ solvents, which can possibly replace more hazardous conventional solvents in many chemical processes, including CO 2 capture [5][6][7] .…”
