Density, Viscosity and Excess Molar Volume of the Aqueous Ionic Liquid Tris(monoethanolamine) Citrate at 293.15–323.15 K

Abstract: A new ionic liquid, tris(monoethanolamine) citrate (TMEAC), was synthesized and characterized by FT-IR spectrometry and 1 H NMR. Densities and viscosities of aqueous TMEAC mixtures were determined at 293.15-323.15 K and atmospheric pressure. The thermal expansion coefficient a, excess molar volume V E m , and excess logarithm of viscosity (ln g) E were calculated to evaluate the properties of the aqueous TMEAC ionic liquid. Correlation equations were fitted using these data for the calculation of density and v… Show more

“…55 A similar observation was reported by Zhang et al in the excess molar volume curves of aqueous ionic liquid tris-(monoethanolamine) citrate (TMEAC). 56 Hydrogen bonding, dipole−dipole, or dipole−induced dipole interactions can result in negative V E values. In addition, packing can contribute to the negative values because of the filling effect of smaller molecules in the solvent mixture.…”

“…Also, density, refractive index, and UV spectra measurements of solutions are expected to shed some light on the solute−solvent interactions and configuration of their mixtures. 26−29 Other thermodynamic properties including molal volume, ionic association, and polarizability were investigated for ionic liquids, 24,25 especially for imidazolium ionic liquid surfactants. 26−29 The present work aims to study the synthesis and characterization of some cationic surfactants.…”

“…Methods for CMC determination include conductivity, viscosity, surface tension, ion activity, dye incorporation, gel filtration spectrophotometrically, counterion magnetic resonance, and refractive index measurements. Solvation of different cationic surfactants in different solvents was investigated before, where CMC was measured with different methods. Also, density, refractive index, and UV spectra measurements of solutions are expected to shed some light on the solute–solvent interactions and configuration of their mixtures. Other thermodynamic properties including molal volume, ionic association, and polarizability were investigated for ionic liquids, , especially for imidazolium ionic liquid surfactants. …”
