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.
