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