Abstract

The speed of sound in octane + dodecane + hexadecane liquid mixture was measured within the temperatures from 298 to 433 K and at pressures from 0.1 to 100.1 МPа with an uncertainty 0.1%. Deviations of speed of sound from a mole fraction average have been calculated using known symmetric and asymmetric models. Density, isobaric expansion coefficient, isobaric and isochoric heat capacity, isothermal compressibility for the liquid mixture octane + dodecane + hexadecane of six compositions were evaluated from speed of sound data in the temperature range from 298 to 393 K at pressures up to 100 МPа. The calculated densities were fitted with a Tait equation.
