Cibulka correlation for ternary excess/deviation properties of C2mim EtSO4 (x1) + acetic or propionic acid (x2) + acetonitrile (x3) systems at different temperatures
(Elsevier, 2017)In this perspective, the main intention is to reveal the possible intra and inter molecular interactions between ternary ionic liquid systems. The excess molar volume (VE123), isentropic compressibility (ks) and deviation ... -
Density and speed of sound measurements of imidazolium-based ionic liquids with acetonitrile at various temperatures
(2014)In the present study, the interactions between acetonitrile and imidazolium-based ionic liquids (ILs) were discussed in terms of density (ρ) and speed of sound (u) measurements. The ILs used in this study were 1-ethyl-3- ... -
Density and speed of sound of 1-ethyl-3-methylimidazolium ethyl sulphate with acetic or propionic acid at different temperatures
(Elsevier, 2014)In this work, new density, ρ, and speed of sound, u, were measured for IL, acetic acid, propionic acid, and their binary systems {IL (x1) + acetic or propionic acid (x2)} at 293.15, 298.15, 303.15, 308.15 and 313.15 K under ... -
Synthesis, characterization and thermophysical properties of ionic liquid N-methyl-N-(2′,3′-epoxypropyl)-2-oxopyrrolidinium chloride and its binary mixtures with water or ethanol at different temperatures
(Elsevier, 2016)A novel ionic liquid, namely, N-methyl-N-(2′,3′-epoxypropyl)-2-oxopyrrolidiniumchloride [Epmpyr]+[Cl]− was synthesized and characterized by different techniques such as NMR (1H and 13C), FTIR, and elemental analysis. The ... -
Thermophysical approach to understand the nature of molecular interactions and structural factor between methyl isobutyl ketone and organic solvents mixtures
(Elsevier, 2017)In this paper, we report the new experimental values of densities, speeds of sound, and refractive indices for four binary mixtures: {methyl isobutyl ketone (MIBK) + dimethyl sulfoxide (DMSO) or acetone or acetonitrile, ...
