“…The kinetic viscosity was calculated using the relation: (1) where ν is the kinematic viscosity, t (s) is its flow time in the viscometer, and A and B are characteristic constants of the used viscometer. The constants A and B were determined by using bidistilled water and benzene as the calibrating liquids.…”

“…Thermophysical properties of multi-component liquid mixtures are essential for process designing as well as for understanding structural and packing changes of molecules in mixtures. The design and operation of processes that involve non-electrolyte mixtures require knowledge of rigorous models or experimental data to represent the non-ideality of mixtures [1].…”

Densities (r), viscosities (h) and refractive indices (nD) of the ternary system cyclohexane + cyclohexanol + cyclohexanone were measured at 293.15, 298.15 and 298.15 K and atmospheric pressure, over the whole composition range. The experimental values of densities and viscosities were correlated with temperature using a linear equation and Guzman equation respectively. Viscosity results were fitted with Grunberg-Nissan equation and Heric-Brewer equation. Different refractive index mixing rules (Arago-Biot, Dale-Glastone, Newton and Lorentz-Lorenz) were studied for this ternary system. The functions of activation of viscous flow were also calculated and their variations with compositions have been discussed.

“…It is also used as raw materials for adipic acid synthesis, as well as precursors of nylon-6 polymers. , This paper is a part of an ongoing project to measure and characterize the properties of mixtures containing cyclic ethers, ketones, and cyclic ketones. In continuation of our work on thermodynamic properties of multicomponent liquid mixtures containing cyclic ether as one of the component, − we report here densities, ρ, speeds of sound, u , and heat capacities, C P , at 293.15, 298.15, 303.15, and 308.15 K and excess molar enthalpies, H E of the tetrahydropyran 1,4-dioxane or (1) + cyclohexanone or cycloheptanone (2) mixtures at 308.15 K.…”

The densities ρ, speeds of sound u, and molar heat capacities C P of tetrahydropyran or 1,4-dioxane (1) + cyclohexanone or cycloheptanone (2) mixtures at 293.15, 298.15, 303.15, and 308.15 K, and excess molar enthalpies, H E at 308.15 K and atmospheric pressure 0.1 MPa have been measured over the entire composition range. The excess molar volumes V E, excess isentropic compressibilities κS E, and excess heat capacities, C P E of the studied mixtures have been determined using the measured experimental data. The observed V E, κS E, H E, and C P E data have been tested in terms of graph theory. The analyses of V E data by graph theory suggest that while tetrahydropyran or 1,4-dioxane exists as a mixture of monomer and dimer; cyclohexanone or cycloheptanone exists as a mixture of open and cyclic dimer. Further, (1 + 2) mixtures are characterized by interactions between oxygen atom/s and hydrogen atom of tetrahydropyran or 1,4-dioxane with hydrogen atom/s and oxygen atom of cyclohexanone or cycloheptanone. The quantum mechanical calculations and analysis of IR spectral data of (1 + 2) mixtures also support this viewpoint. It has been observed that graph theory correctly predicts the V E, κS E, H E, and C p E data of the present mixtures.
