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

Abstract

It has been proven that alcohols can regulate the performance of aviation fuels. In this work, the densities (ρ) and viscosities (η) for the ternary system of isopropylcyclohexane (1) + n-tridecane (2) + n-butanol (3) and the corresponding binary systems have been measured to understand the physical properties of endothermic hydrocarbon fuel with alcohol over the whole composition range at temperatures from 293.15 to 333.15 K under atmospheric pressure (p = 0.1 MPa). The Redlich–Kister equation has been used to fit the excess molar volumes (V m E) and viscosity deviations (Δη) of binary systems, while four semiempirical equations (Singh, Cibulka, Nagata–Tamura, and Redlich–Kister) have been applied to correlate V m E and Δη of the ternary system. For all binary systems, the values of V m E are positive. The values of Δη for binary systems containing n-butanol are all negative. For the ternary system, the values of V m E are all positive and the values of Δη are all negative over the entire concentration range. All results have been interpreted with the perspective of intermolecular interaction and structural effect.

Viscosity, Interfacial Tension, and Density of Binary-Liquid Mixtures of n-Hexadecane with n-Octacosane, 2,2,4,4,6,8,8-Heptamethylnonane, or 1-Hexadecanol at Temperatures between 298.15 and 573.15 K by Surface Light Scattering and Equilibrium Molecular Dynamics Simulations

“…In addition, a systematic variation of mixture components to evaluate the impact of carbon-chain length, branching, or hydroxylation is required so that the scientific findings can be directly transferred to other fluid mixtures. While experimental data for hydrocarbon-based binary mixtures are available in the literature, the investigated temperatures are often limited to 400 K and no such systematic variations are available. − …”

Density and Viscosity of the Ternary System Pinane + n-Dodecane + Methyl Laurate and Corresponding Binary Systems at T = 293.15–333.15 K

“…Due to the dispersion force between nonpolar molecules, the overall V m E of the system is positive; as a consequence of dispersion force, it decreases with rising temperature. This phenomenon can also be found in systems of isopropylcyclohexane + n -tridecane and n -dodecane + butylcyclohexane. , …”

“…This phenomenon can also be found in systems of isopropylcyclohexane + n-tridecane and n-dodecane + butylcyclohexane. 29,30 For the binary systems of pinane (1) + methyl laurate (2) and n-dodecane (1) + methyl laurate (2) (Figure 2b,c), the maxmium values of V m E all appears at around x 1 = 0.6. Compared with the system of pinane (1) + n-dodecane (2), the maxmium values of V m E for systems that contained methyl laurate are larger.…”

Densities and Viscosities of the Ternary Mixtures of Decalin (1) + n-Hexadecane (2) + 1-Butanol (3) and Corresponding Binary Systems

“…A similar situation was examined for the system of isopropylcyclohexane (1) + n-tridecane (2). 66 The comparison of data in the literature with those in our work was also carried out. 43,50,67 As shown in Figures S3 and S4, the tendencies of densities and excess molar volumes in this work match well with the literature data.…”

“…It is worth noting that the viscosity deviations keep negative for the whole composition range at 293.15 K, illustrating that the non-interaction force is temperature-sensitive. A similar situation was examined for the system of isopropylcyclohexane (1) + n -tridecane (2) …”
