“…The two-parameter McAllister three-body (MAC3) and three-parameter McAllister four-body (MAC4) equations, on the other hand, were correlated with the kinematic viscosities, ν ; the latter being related to η and densities, ρ, as ν = η/ρ. All the experimental data of η and ν in use were collected from previous publications by different authors. − Moreover, the results of ρ and η correlations were also compared with the equations of simple polynomials and the Jouyban-Acree model of different degrees. The correlating abilities of each of the above models were tested by calculating the standard percentage deviation, σ%, between experimental and calculated values as Here, Y exp and Y cal refer to experimental and calculated ρ, η, or ν; n represents the number of data points and p is the number of coefficients taken.…”

The present study mainly reports the theoretical estimation of dynamic viscosities, η, and kinematic viscosities, v, for 150 binary liquid systems comprising different categories of organic compounds: alkanes, alcohols, aromatics, ketones, esters, and amines as well as some other typical organics containing O, N, and S atoms: acetonitrile, nitromethane, nitrobenzene, pyridine, 4-methylpyridine, dimethyl sulfoxide, and sulfolane. Computations were performed following two different approaches. The first methodology corresponded to correlative models of Grunberg-Nissan, Hind, Heric, Ausländer, McAllister three-body and four-body equations as well as the Jouyban-Acree model. Fitting capabilities of simple polynomial equations and that of the Jouyban-Acree model for density and viscosity correlations were also tested for different degrees of polynomials. Accuracies of different models were analyzed by comparing values of σ% as well as overall σ% for different categories of binary systems investigated. Correlative models with a higher number of parameters can yield satisfactory results, the quality of correlations being dependent on the symmetry of model equations, molecular interactions, and the number of available data points also. On the other hand, the second methodology belongs to a predictive model: the UNIFAC-VISCO. Applicability of existing αnm parameters in predicting dynamic viscosities of the selected binary mixtures is tested by calculating the respective AAD%. The results for AAD% and OAAD% values suggest that the UNIFAC-VISCO model can yield very good results in predicting both the dynamic and kinematic viscosities of liquid mixtures. Finally, 34 pairs of new group–group interaction parameters, αnm, of the UNIFAC-VISCO model were determined with various amines, acetonitrile, nitromethane, nitrobenzene, pyridine, dimethyl sulfoxide, sulfolane, etc. as one of the components. The availability of these new group interaction parameters would contribute further in extending the range of applicability of the conventional UNIFAC-VISCO model, even to a wider range of multicomponent liquid systems.

The aim of this research is the experimental determination of density, viscosity, refractive index and speed of sound for binary mixtures of the ester ethyl acetate and alcohols. Experimental measurements were carried out for two systems with 1-propanol and 1-butanol at atmospheric pressure and in a temperature range 288.15 - 323.15 K. Results of experimental measurements were further used to determine excess molar volumes, viscosity deviations, refractive index deviations, and excess isentropic compressibility for each investigated mixture. These calculated data were correlated using the empirical Redlich-Kister equation. Positive values of the excess molar volume and isentropic compressibility appear for both analysed systems, while values of viscosity and refractive index deviations are negative. The structure and specific characteristics of different molecules in considered mixtures and determined non-ideal behaviour allow the insight into the possible type of interactions in the mixture, interstitial accommodation and structural effects.

“…In chemical industry, materials are usually handled in fluid form and, hence, the physical, chemical and transport properties of fluids assume prime importance in research. The data on some of the physical properties associated with the liquids and liquid mixtures like density, viscosity, refractive index, surface tension and speed of sound find extensive application in solution theory and molecular dynamics [7][8][9][10][11][12][13]. The evaluated data of excess thermodynamic functions of liquid mixtures give an insight of molecular interactions which can be used to test thermodynamic models [14].…”

The density, viscosity and speed of sound of pure p-anisaldehyde and some alkanols, for example, methanol, ethanol, propan-1-ol, propan-2-ol, butan-1-ol, butan-2-ol, 2-methylpropan-1-ol, and the binary mixtures of p-anisaldehyde with these alkanols were measured over the entire composition range at 303.15 K. From the experimental data, various thermodynamic parameters such as excess molar volume (V E ), excess Gibbs free energy of activation (ΔG* E ), and deviation parameters like viscosity (Δη), speed of sound (Δu), isentropic compressibility (Δκ s ), are calculated. The excess as well as deviation parameters are fitted to Redlich-Kister equation. Additionally, the viscosity data for the systems has been used to correlate the application of empirical relation given by Grunberg and Nissan, Katti and Chaudhari, and Hind et al. The results are discussed in terms of specific interactions present in the mixtures.
