Densities and Viscosities for the Ternary System of 1,2,3,4-Tetrahydronaphthalene + Isopropylcyclohexane + Cyclopropanemethanol and Corresponding Binaries at T = (293.15 to 343.15) K

Abstract

Measurements on density and viscosity at atmospheric pressure for the ternary system 1,2,3,4-tetrahydronaphthalene (1) + isopropylcyclohexane (2) + cyclopropanemethanol (3) and three corresponding binary systems from (293.15 to 343.15) K have been carried out over the whole composition range. The excess molar volumes (V m E) and viscosity deviations (Δη) of the ternary system have been derived from the experimental data and then fitted to the Cibulka, Singh, Redlich–Kister, and Nagata–Tamura equations, respectively. The binary subsystems were correlated by Redlich–Kister equation. For the system of 1,2,3,4-tetrahydronaphthalene + isopropylcyclohexane, the curve of the V m E reveals a wing shape. The V m E values are positive for the other two binary systems of 1,2,3,4-tetrahydro­naphthalene + cyclopropane­methanol and isopropyl­cyclohexane + cyclopropane­methanol. While the value of Δη for all three binary systems is negative over the entire composition range. The results are interpreted with molecular interactions and structural effects.

“…21−28 Han et al, 24 Singh et al, 25 and Ma et al 26 and co-workers investigated four semiempirical equations (i.e., Cibulka, Singh, Redlich−Kister, and Nagata−Tamura equations) to represent V E and Δη of several nonaqueous ternary systems. 27 Zhao et al 28 used a modified Jouyban−Acree model including the effects of temperature to represent the property data of the ternary systems.…”

“…In addition, the correlations and prediction of volumetric properties and viscosities of ternary mixtures using empirical models is an active area of research in development. There are several semiempirical equations that have been applied to correlate the experimental ternary results in the literature. − Han et al, Singh et al, and Ma et al correlated the excess molar volume ( V E ) and viscosity deviation (Δη) of different ternary systems with Redlich–Kister and Cibulka equations. Guo and co-workers investigated four semiempirical equations (i.e., Cibulka, Singh, Redlich–Kister, and Nagata–Tamura equations) to represent V E and Δη of several nonaqueous ternary systems .…”
