Acoustic and thermodynamic properties of a binary liquid cyclohexane $+$ n-hexadecane mixture

The speed of sound in a binary liquid cyclohexane $+$ n-hexadecane mixture was investigated by direct measurement of the pulse propagation time at $298$–$433$ K and pressure range of $0.1$–$100.1$ MPa. The maximum measurement uncertainty was $0.1\%$. The density, isobaric expansion coefficient, isobaric and isochoric heat capacity, and isothermal compressibility of the mixture of three compositions were determined at $298$–$348$ K and pressure range of $0.1$–$80$ MPa based on the data on speed of sound. The excess molar volume and coefficients of the Tait equation were calculated in the above ranges. Thermodynamic properties of the mixture are presented in the tabular form.
