“…In Figure , the natural logarithm of the viscosity of the samples at 20 °C is plotted as a function of the mole ratio of 1-decanol. The data are compared with theoretical predictions using the linear relation for binary mixtures: where η is the Newtonian viscosity of the solution, η 1 and η 2 denote the viscosities of the pure components, and x 1 and x 2 denote the corresponding mole fractions. As can be seen in the figure, some deviation from ideality is revealed in these data, and according to ref indicate a slightly negative deviation from Raoult's law.…”

The solutions were checked for possible non-Newtonian flow, but no deviation from Newtonian behavior was detected for any of the samples for shear rates ranging from 1 to 1000 s -1 .…”

Microemulsion samples of an ethoxylated polymethylsiloxane surfactant, water, and 1-dodecanol or 1-decanol as the oil component are investigated using pulsed field gradient NMR to determine the components' self-diffusion coefficients. It is demonstrated that the structure of the liquids depends heavily on their composition, in that, for low water content, the structure is water-in-oil (w/o), gradually changing to a bicontinous structure in a concentration range ca. 40-60 wt % water, and, finally, to an oil-in-water (o/w) structure for more water rich samples. In the water poor samples, the surfactant molecules apparently do not form extended aggregates (inverted micelles). In the water rich samples, the surfactant and oil (if present) form ordinary micelles, and it is demonstrated for the binary water/surfactant system that the micelles are spherical at very low surfactant concentrations and grow into oblate (disk) shaped aggregates at surfactant concentrations above ca. 5 wt %. From density and viscosity measurements of binary mixtures of oil (1-decanol) and surfactant, it is demonstrated that these components form solutions that are not far from ideal.

Composition-dependent association behavior in the mixture of isopropanol and trichloromethane: a volumetric, vibration spectroscopic and quantum chemical study

et al. 2015

View full text Add to dashboard Cite

Herein the intermolecular associative behaviors in the binary mixture of isopropanol and trichloromethane have been studied via a combined excess volumetric, vibration spectroscopic and quantum chemical approach. The densities of the mixture studied were obtained at T = (283.15 to 323.15) K and at atmosphere pressure. From the experimental data, the excess molar volumes were obtained as a function of composition, and their corresponding curves fitted show a distinct sigmoidal feature at each temperature, which can be considered in terms of free packing effects and the presence of intermolecular self-and cross-associated interactions competition. Meanwhile, the composition-dependent association behavior was further ascertained via vibration spectroscopic technology. In addition, the geometric structures, interaction energies, electron topology properties and Gibbs free energy changes of the self-and cross-associations in the mixture studied were investigated via quantum chemical calculations. The computational results have been also interpreted in term of the composition-dependent association behavior in the mixture studied.

“…However, to the best of our knowledge, the ERASModel has not yet been tested for the mixtures in this study. Thermodynamic properties of binary mixtures of chloroalkanes with amines have been studied by other authors [10][11][12][13][14][15][16][17][18][19][20][21].…”

Volumetric Properties of Chloroalkanes + Amines Mixtures: Theoretical Analysis Using the ERAS-Model

et al. 2009

View full text Add to dashboard Cite

In this study, experimental data of excess molar volumes of {dichloro-methane (DCM), or trichloromethane (TCM) + n-butylamine (n-BA), or +s-butylamine (s-BA), or +t-butylamine (t-BA), or +diethylamine (DEA), or +triethylamine (TEA)} mixtures as a function of composition have been used to test the applicability of the extended real associated solution model (ERAS-Model). The values of the excess molar volume were negative for (DCM + t-BA, or +DEA, or +TEA and TCM + n-BA, or +s-BA, or +DEA, or +TEA) mixtures and present sigmoid curves for (DCM + n-BA, or +s-BA) mixtures over the complete mole-fraction range. The agreement between theoretical and experimental results is discussed in terms of crossassociation between the components present in the mixtures.
