Densities, refractive indices, and excess molar volumes of the ternary systems water + methanol + 1-octanol and water + ethanol + 1-octanol and their binary mixtures at 298.15 K

Experimental and predicted refractive index properties in ternary mixtures of associated liquids

“…The previous studies [18][19][20][21] of water with different alcohols in binary mixtures indicate that applying different mixing rules does not allow to obtain a good agreement with experimental data on the refractive index. The non-ideal thermodynamic behavior in these mixtures is linked to the presence of hydrogen-bonding interactions that occur between molecules of different species (cross-association).…”

Comparison of Methods for Predicting the Compositional Dependence of the Density and Refractive Index of Organic–Aqueous Aerosols

“…Table S1. [25][26][27][28][29][30][31][32][33] The organic species considered included alcohols, nitriles, carboxylic acids, diols, sulphoxides, amides, ethers and polyols. As the molar refraction mixing rule requires knowledge of mixture density in order to predict RI, data sets were selected based on the availability of paired measurements of RI and density for each different mass fraction of the water/organic mixture.…”

Density, dynamic viscosity, and derived properties of binary mixtures of methanol or ethanol with water, ethyl acetate, and methyl acetate at T=(293.15, 298.15, and 303.15)K

“…15, 298.15, and 303.15) K. Experimental data were used to calculate excess molar volumes, viscosity deviations, and excess free energy of activation over the entire mole fraction range. Although these systems have been studied previously, most have been determined only at one temperature (T = 298.15 K) [4][5][6]. For the systems {x 1 ethanol + (1 À x 1 ) ethyl acetate}, and {x 1 methanol + (1 À x 1 ) ethyl acetate} [7], the techniques used to measure densities and viscosities were the pycnometer for measuring the density and digital stopwatch for measuring the flow time of the liquids, giving big differences in the excess properties.…”

We have used reagents purer than the ones used by Arce et al [4] and Nikam et al [7]. In this work, the influence of temperature on these systems has been studied, using apparatus with major precision.…”
