Thermodynamic properties of binary liquid mixtures of n-octane + n-hexadecane
Talgat S. Khasanshin, Vladimir S. Samuilov and Alexander P. Shchamialiou
The speed of sound data over a wide range of temperatures and pressures as well as the density and the isobaric heat capacity data at atmospheric pressure for mixtures of n-octane + n-hexadecane were used to evaluate the thermodynamic properties. Detailed tables with the densities, isobaric and isochoric heat capacities, isobaric thermal expansion coefficient, and isothermal compressibility for mixtures of n-octane + n-hexadecane with the mole fraction of octane of 0.25, 0.50, and 0.75 at temperatures from (298 to 393) K and pressures from (0.1 to 100) MPa are given. The calculated densities were fitted with a modified Tait equation. The excess molar volume was estimated.
