Studies of viscosity and excess molar volume of binary mixtures

Calculation of the Viscosity of Binary Liquids at Various Temperatures Using Jouyban-Acree Model

“…Available viscosity data of binary liquid mixtures from the literature [5][6][7][8][9][10][11] were collected and used to build a database. All experimental data were used as reported in the literature and only one datum corrected as there was a typographical error.…”

“…Equation 7 has been employed in a series of papers published by Oswal and Desai and produced accurate correlation for the viscosity of binary solvents. [5][6][7][8] The applications of the model could be extended for calculating the viscosity of binary solvents at different temperatures as: (8) Where h 1,T and h 2,T are viscosity of pure liquids at temperature T and A 0 -A 2 are the model constants. These constants are computed by a least squares analysis.…”

“…Grunberg and Nissan 2) proposed an extended form of the Arrhenius model for better representation of experimental data. Redlich-Kister extension 3) has been used in many papers [4][5][6][7][8][9][10][11][12] for expressing the non-ideality of the mixtures in arithmetic and logarithmic scales at a fixed temperature. To the best of our knowledge, there is no published model for calculating the viscosity of liquid mixtures at various temperatures and the aim of this work is to present such a model.…”

Viscous synergy and antagonism and isentropic compressibility of ternary mixtures containing 1,3-dioxolane, water and monoalkanols at 303.15K

“…Viscosity and density of these ternary liquid mixtures are used to understand molecular interactions between the components of the mixture to develop new theoretical models and also for engineering applications [20,21]. The thermodynamic properties of various alkanols have been studied in numerous solvents [22][23][24][25][26]. In the systematic investigation of the properties, we have reported viscosities, densities and speeds of sound in our previous papers [27][28][29][30][31][32][33].…”

Thermophysical Properties of Binary Liquid Mixtures of Acetronitrile with 2- Ethoxyethanol and 2- Butoxyethanol at Temperatures 293K, 303K and 313K: Experimental and Computational Study

“…Generally the positive values of deviation viscosity (∆η) indicate the predominance of hydrogen bonding interaction between unlike molecules over the dissociation effects of the mixing components [15]. It is known that the strength of the molecular hydrogen bonding is not only the factor influencing viscosity deviation (∆η) in the liquid mixture, the molecular size and shape of the components and average degree of association is equally important factor [16].…”
