Volumetric Properties for (Ionic Liquid + Methanol or Ethanol or 1-Propanol + Nitromethane) at 298.15 K and Atmospheric Pressure

Abstract

The densities of the ternary systems {1-butyl-3-methylimidazolium methyl sulfate ([BMIM]+[MeSO4]−) + methanol or ethanol or 1-propanol + nitromethane} were measured at the temperature 298.15 K, and the ternary excess molar volumes, V 123 E, were calculated . The V 123 E values are negative for all mole fractions of the ionic liquid (IL) and increase with increasing mole fraction of IL. The Cibulka equation was used to correlate the ternary excess molar volumes using the Redlich−Kister parameters for the binary systems obtained from the literature. There is a good correlation between the Cibulka equation and the experimental V 123 E data.

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 purity of the solvents was assessed by a comparison of the experimental density, speed of sound and refractive index with literature values at T = 298.15 K and are given in table 1. Densities, speed of sound, and refractive indices of all of the chemicals at T = 298.15 K have a good agreement with the corresponding literature values [1,2,4,6,[9][10][11]13,[21][22][23][24][25][26][27][28][29][30][31][32].…”

“…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.…”

Interaction studies of methyl acetate in aqueous solutions of quinoxaline derivatives: Effect of temperature and concentration

“…Thus, the results from these studies can be utilized to synthesize the new pharmaceutically active compounds on an industrial scale. The present work is a continuation of our research group's studies on thermo-physical and thermodynamics properties of solutions [24][25][26][27][28][29][30][31][32][33][34][35][36]. The structure of the studied quinoxaline derivatives is given in Fig.…”
