Density, ρ, and viscosity, η, of pure components of
2-aminoethanol, 1-butanol, and 3-amino-1-propanol, along with the
binary mixtures of {x
12-aminoethanol + x
21-butanol}, {x
13-amino-1-propanol + x
21-butanol}, and
{x
13-amino-1-propanol + x
22-aminoethanol}, were determined over the whole composition
range and in the temperatures of 293.15–333.15 at ambient pressure p = 86 kPa. The experimental values of density and viscosity
have been used to calculate the excess molar volume, V

coefficient, α, excess thermal expansion coefficient, αE, and viscosity deviation, Δη, of binary mixtures.
The results show that excess molar volumes of the mixtures are negative
in the whole composition range and increase with increasing temperature.
Viscosity deviations, Δη, of two former mixtures are negative
over the entire composition range and decrease with increasing temperature,
while the Δη values of the later mixture are positive
over the entire composition range and decrease with the increasing
temperature. The excess properties were correlated by the Redlich–Kister
equation, and their fitting parameters and standard deviations were
determined. The excess molar volumes were also correlated by applying
the Prigogine–Flory–Patterson (PFP) model, and their
interaction parameters, χ12, were obtained.
