“…Experimental densities and viscosities, obtained from the measurements for liquid pure compounds and standard samples, have been presented in the Supporting information (SI) Table S1 together with the literature values. − We have found a good agreement between the experimental density data obtained in this work and the literature data for all chemicals with an average absolute relative deviation (AARD) within 0.20%, as shown in Figure . Among them, large deviations of density are from EGEE compared with the work of Carvalho et al, which may be due to the difference of water content and purity for this solvent.…”

Blends of amines with alkoxyethanols have been potentially used as alternative absorbents to conventional aqueous amines for energy-efficient CO2 capture, due to the lower specific heat capacity and enthalpy of vaporization of organic solvents than water. In this work, densities and viscosities were measured at atmospheric pressure for binary liquid mixtures of 2-(methylamino)ethanol (MAE) + 2-methoxyethanol (EGME), MAE + 2-ethoxyethanol (EGEE), and MAE + 2-butoxyethanol (EGBE) over the entire composition range and at temperatures of 293.15–353.15 K. The excess molar volume and viscosity deviations were also calculated and fitted by the Redlich–Kister equation. The calculated values of density and viscosity from the proposed correlations are in good agreement with the experimental values, with average absolute relative deviations within 0.06 and 1.23% for density and viscosity, respectively. The variations of excess or deviation properties with temperature and components were also discussed in terms of intermolecular interactions and structural effects.

“…DEA, being the least bulky branched amine, therefore has strongest interaction with 2-EtO-EtOH. Interstitial fittings of smaller molecules into molecules with larger molecular volumes have also been reported in binary mixtures of ethylacetoacetate and (C 4 -C 6 ) aliphatic ketones by Izonfuo and Kemeakegha [42], for binary mixtures of -methylpyrrolidone with (C 1 -C 10 ) alkan-1-ols [43], formamide and ethanol mixtures [44,45], and dimethylsulfoxide and alcohols [46][47][48]. In the binary mixed solvents with compositions above 0.50 mole fraction of 2-ethoxyethanol, intermolecular hydrogen bonding between unlike molecules predominates and the trend is similar to that in the binary mixtures of 2-methoxyethanol with the named amines.…”

Densities of binary mixtures of 2-methoxyethanol (2-MeO-EtOH) and 2-ethoxyethanol (2-EtO-EtOH) with hexylamine (HLA), diethylamine (DEA), triethylamine (TEA), tert-butylamine (TBA), aniline (ANL), and benzylamine (BLA) have been determined at varying compositions of the alkoxyalkanols at 298.15 K. The excess molar volumes, VE, of the binary mixtures were calculated from the experimental density data of the mixtures and the component single solvents. The calculated excess molar volumes were fitted into the Redlich-Kister polynomial to obtain the fitting coefficients and standard deviations. The excess molar volumes of the binary mixtures of all the solvent systems investigated were negative over the entire range of the solvents composition. The negative values were attributed to stronger hydrogen bond formations between the unlike molecules of mixtures than those between the like molecules of the pure components. The magnitude of the excess molar volumes of the binary mixtures of 2-methoxyethanol and the aliphatic amines were in the order TBA > TEA > DEA > HEA. For the two aromatic amines, the magnitudes were in the order BLA > ANL. For binary mixtures of the amines and 2-ethoxyethanol, the magnitudes were in the order DEA > TEA > TBA > HEA at compositions where the mole fraction of 2-EtO-EtOH was ≤0.5 and TBA > TEA > DEA > HEA above 0.5 mole fraction of 2-EtO-EtOH.

“…As a result, the values of V E become more negative with increasing temperature. In the present investigation, the negative κs E values indicate that the dipole-dipole interactions between the components of the mixtures, resulting the formation of electron donoracceptor complexes [18]. Thus, the formation of complexes between the components of the mixtures leads to a decrease in the intermolecular distances and increase in sound velocities, thereby decreasing the isentropic compressibilities of the mixtures [19].…”

Analyses of each of the three contributions namely, interactional, free volume and P* to V E show that P* contribution is negative for all systems expect p-chlorotoluene, which has positive P* contribution and interactional contribution is positive for all systems. Further, the free volume effect is negative for all the mixtures. The variations of these parameters with composition and temperature are discussed in terms of intermolecular interactions prevailing in these mixtures.
