“…13−15 2-Aminoethanol is a colorless viscous liquid widely used in the pharmaceutical industries, for carbon dioxide absorption, and for controlling the pH in the reaction medium. 15 An extensive survey of the literature showed that a few studies have been carried out on measurements of thermophysical and thermodynamic properties of binary mixtures containing EL with different liquids, namely, alcohols, 9 2-alkoxyethanols, 16 C 3 -alkanols, 17 aromatic/alkyl amines, 18,19 and nitrile compounds. 20,21 On the other hand, Resa et al 22 have measured the densities, speed of sound, and refractive index for ethyl lactate with ethyl acetate at 298.15 K. As far as we know, thermophysical and excess thermodynamic properties of binary liquid mixtures of ethyl lactate with substituted ethanols and ethyl acetate at a temperature range of 298.15−323.15 K and at a pressure of 0.1 MPa with Fouriertransform infrared (FT-IR) spectroscopic and computational studies were not reported in the literature.…”

Thus, the present study mainly focused on thermophysical properties (density, speed of sound, and refractive index) and excess thermodynamic parameters ( V E , k s E , and n D E ) of EL with 2-CE, 2-AE, and EA at T = 298.15–323.15 K and at 0.1 MPa together with experimental FT-IR analysis and density functional theory (DFT) calculations.…”

In the present study, measurements of the experimental density (ρ), speed of sound (c), and refractive index (n D ) of binary liquid mixtures of ethyl lactate (EL) with 2-aminoethanol (2-AE), 2-chloroethanol (2-CE), and ethyl acetate (EA) have been carried out within the temperature range from 298.15 to 323.15 K with an interval of 5 K and at 0.1 MPa. Excess volume (V E ), isentropic compressibility (k s ), excess isentropic compressibility (k s E ), and excess refractive index (n D E ) for the above liquid mixtures were calculated from the experimental measurements and they were correlated with the Redlich−Kister equation. Also, we obtained good fitting results in the computation of the density with perturbed chain statistical associating fluid theory equation of state and predictive results in the computation of the refractive index and speed of sound with several mixing rules and Nomoto's relation, respectively. Further, we measured the Fouriertransform infrared (FT-IR) spectral data of pure liquids and their mixtures at different concentrations and simulated the molecular interactions using density functional theory (DFT) calculations for the 3 sets of binary systems with the ADF 2020.102 package at the GGA BP86-D3 level of theory with TZP. Apart from these, the type and nature of molecular interactions and structural effects were studied between the component molecules with the aid of excess thermodynamic properties, FT-IR measurements, and DFT calculations.

A model assuming that the formation of dimers determines the acoustic properties of liquid mixtures, in the inert solvent cyclohexane, was applied to describe the observed dependences of sound speed on composition. The dimerization constants were estimated. The results allow one to propose that the solutes tend to form associates larger than dimers in concentrated solutions, while in dilute systems solute–solvent interactions play an important role.Electronic supplementary materialThe online version of this article (doi:10.1007/s10953-017-0656-1) contains supplementary material, which is available to authorized users.
