“…The purities of the reagents were greater than 0.99 mole fraction analyzed by gas chromatography and were sufficient to determine the thermophysical property behaviors of studied systems at different temperatures and atmospheric pressure. We also checked the purities of chemicals by comparing their physical properties such as densities, viscosities, and refractive indices with those found in the literature, ,− as pointed in Table . Our measured densities, refractive indices, and viscosities are in good agreement with the reported values in the literature within average absolute percentage deviation (AAPD) of 0.022; 0.025, and 0.033%, respectively.…”

The aim of this work is experimental determination of density, ρ, refractive index, n D, viscosity, η, and their derivatives for four binary systems containing glycerol in the mixture with butanol isomers: 1-butanol, 2-butanol, isobutanol, and tert-butanol. Experimental results were carried out for all concentration ranges at atmospheric pressure and at a temperature interval of 293.15–318.15 K except for the mixtures with tert-butanol because of high melting temperatures, so the measurements were made from 303 K. Results of experimental measurements were further used to estimate, for each investigated mixture, excess molar volumes, partial molar volumes, apparent molar volumes, thermal isobaric expansibilities, excess thermal expansibilities and partial molar volumes at infinite dilution, the viscosity deviations, and the excess energies of activation. In addition to that, the infrared spectra of all the systems have been recorded at three concentrations at room temperature. The excess molar volumes V E and excess thermal expansitivities for all investigated systems are found negative over the whole composition range and at all temperatures studied, and deviations from ideality increase with increasing temperature. Negative values of viscosity deviation appear for all systems, but contrary to the excess molar volumes, the deviations from ideality decrease with temperature rising. The excess molar calculated properties were well fitted using the empirical Redlich–Kister polynomial. All the properties measured and calculated in this work have shown a significant influence of the structure of the molecules including the size, shape, and the position of the hydroxyl groups of the components. As expected, the infrared spectra of these binary mixtures prepared with these four butanol isomers show strong hydrogen bonding capability.

“…The acetate, on the other hand, due to the existence of the CO functional group, can be only an acceptor of the hydrogen. The previous research − showed that this kind of compound combination results in positive deviations in V E and confirmed the presence of weak hydrogen bonds between heteromolecules , in the mixture which cannot overpower the expansion of the volume due to the disruption of interactions between molecules of alcohol and negative structural effects with higher and branched alcohols. From Figure , it also can be concluded that not only branching, but the length of the lateral alkyl group itself has a large influence, which is noticeable by the increased V E values for the system with isobutanol compared to the system with isopentanol.…”

Three binary mixtures consisting of isoamyl acetate and 1-butanol or isobutanol or isopentanol were experimentally investigated in terms of their density, viscosity refractive index, and ultrasonic speed of sound, in the temperature range from 288.15 to 323.15 K and at atmospheric pressure. The choice of mixtures was based on their potential for practical application. From experimental data, excess molar volume, viscosity deviation, excess molar Gibbs free energy of activation of viscous flow, deviation in refractive index, and deviation in isentropic compressibility are calculated, correlated with the Redlich–Kister equation and used for better understanding of molecular interactions between the mixture components. Also, partial molar volumes, excess partial molar volumes, and partial molar volumes at infinite dilutions were calculated to elucidate the nonideal behavior of the investigated mixtures. Since the mixtures were investigated both from the theoretical point of view and with the aspect for practical application, the modeling of two key properties, viscosity and excess molar volume, was performed with different models and approaches, and the results are compared with experimental values.
