Densities and Viscosities of Ternary System n-Dodecane (1) + Bicyclohexyl (2) + n-Butanol (3) and Corresponding Binaries at T = (293.15 to 333.15) K

Abstract

Densities (ρ) and viscosities (η) of ternary system n-dodecane + bicyclohexyl + n-butanol and three corresponding binary systems, n-dodecane + bicyclohexyl, n-dodecane + n-butanol, and bicyclohexyl + n-butanol, were measured at temperature range from 293.15 to 333.15 K in detail. Densities were obtained using a vibrating-tube densimeter. Viscosities were determined using an automatic microviscometer based on the rolling ball principle. The excess molar volumes (V m E ) and the viscosity deviations (Δη) of each mixture were calculated with the measured data. The V m E and Δη values of three binary systems were fitted to the Redlich−Kister equation, and those of the ternary system were fitted to Nagata−Tamura, Singh, Clibuka, and Redlich−Kister semiempirical equations. The V m E values are negative for the binary system of n-dodecane + bicyclohexyl with the minimum at about x = 0.5, while those of binary systems n-dodecane + n-butanol and bicyclohexyl + n-butanol are positive over the entire concentration range. For the ternary system, the V m E values are subtotal positive and the Δη are negative over the entire concentration range. The nonideal behaviors of the mixtures are explained by physical interactions and structural effects between mixture components.

Density and Viscosity of Binary Mixtures Composed of Anisole with Dodecane, Hexadecane, Decalin, or 1,4-Dioxane: Experiments and Modeling

“…All pure compound data obtained in this work are shown in Table . Our results are in agreement with data from the literature for anisole, , dodecane, − hexadecane, − decalin, , and 1,4-dioxane. , The comparison of experimental densities is shown in Figure a, and it is observed that all absolute relative deviation (ARD(%)) values are below 0.2%, as presented in Figure b. Viscosity measurements are shown in Figure a with all ARD(%) values within 4%, as observed in Figure b.…”

“…In eq 1, x s is the sample purity and ξ is the assumed fractional density difference between the compound of interest and the impurity. 18 The viscosities (η) of all samples were measured with a falling ball viscometer (Anton Paar AMVn) under the same conditions. The efflux deflected time and temperatures of the apparatus are accurate to ±0.001 s and ±0.01 K, respectively.…”
