Mixing Functions of Binary Liquid Mixtures of Cyclic Alcohols and Ethylene Glycol at T = 293.15–318.15 K and Pressure P = 0.1 MPa: An Approach from the Volumetric and Viscometric Properties

Mixing Functions of Binary Liquid Mixtures of Cyclic Alcohols and Ethylene Glycol at T = 293.15–318.15 K and Pressure P = 0.1 MPa: An Approach from the Volumetric and Viscometric Properties

In the present work, densities (ρ) and viscosities (η) of binary liquid mixtures of cyclic alcohols and ethylene glycol have been measured over the whole composition range at different temperatures (293.15–318.15 K), under atmospheric pressure (0.1 MPa). The mixing functions like excess molar volume...

Description
Summary:In the present work, densities (ρ) and viscosities (η) of binary liquid mixtures of cyclic alcohols and ethylene glycol have been measured over the whole composition range at different temperatures (293.15–318.15 K), under atmospheric pressure (0.1 MPa). The mixing functions like excess molar volumes (V m E) and viscosity deviation (Δη) have been calculated and further fitted with the Redlich–Kister equation. For the system of cyclopentanol (2) + ethylene glycol (1), the V m E values were asymmetric and positive and reach a maximum around x 2 = 0.7, and for the rest of the system, these maxima appear around 0.6, 0.5, and 0.58, respectively. Δη values are negative and were also correlated with the algebraic Redlich–Kister equation.
