“…The present work is a continuation of earlier studies of the above-mentioned system [2] (a study of 1-nonanol has been recently reported as well [3]). The system under test is so much more interesting because it exhibits limited miscibility characterized by the upper critical temperature point (UCTP).…”

“…In other words, the differences between the experimental absorption and the classical values are almost composition independent. Moreover, both above-mentioned curves are reminiscent of the η(x) curve [2] (in this case, however, there is a lack of a relative minimum for mixtures with a small concentration of 1,2-ethanediol). Thus, the shear viscosity is a predominant property in this case.…”

“…From the measurement results and the data on density, shear viscosity, and speed of sound reported previously [2], the difference between the experimental absorption and classical values, the volume viscosity, and the ratio of the volume and shear viscosities are calculated. Their composition dependences are analyzed and discussed in terms of previous results reported in [2].…”

Ultrasonic absorption coefficients for (1,2-ethanediol + 1-nonanol) have been measured for various mole fractions between 0 and 1 at 298.15 K. The measurements of the absorption coefficients have been performed by the standard pulse technique in the frequency range of (30 to 80) MHz. The volume viscosity is derived from the measured quantities. The dependence upon the mixture composition is discussed.

Chemical Thermodynamics of Ultrasound Speed in Solutions and Liquid Mixtures

A comprehensive formalism is developed to treat thermodynamically speed of ultrasound data for solutions and liquid mixtures. For solutions, the apparent speed of ultrasound of a solute is introduced and proposed to take the place of empirically defined quantities. The partial speed of ultrasound of a solute is defined and related to the partial molar volume and partial molar isentropic compression. For liquid mixtures, the concept of speed of sound before mixing pure liquids is presented and used to define the change in speed of ultrasound upon ideal mixing, which is predicted to be generally a negative quantity. A new thermodynamic equation is derived linking the values for excess speed of ultrasound, excess molar volume and excess molar isentropic compression of a mixture, and its applications are discussed. Ideal and excess apparent speeds of ultrasound, as well as ideal and excess partial speeds of ultrasound, are defined for substances making up a liquid mixture. Accurate speeds of ultrasound in 31 mixtures of water with the amphiphile 2-(ethylamino)ethanol at 293.15 K are reported. These data are used to demonstrate the ability of the apparent speed of ultrasound to describe the impact of solutes on sonic properties of solutions and the advantages of analysing thermodynamic properties of binary liquid mixtures in terms of the dependence on composition of Balankina's ratios between excess and ideal values. It is concluded that the new thermodynamic functions defined for speeds of ultrasound in solutions and liquid mixtures give, at the least, equivalent information on molecular aspects to the usual functions related to the isentropic compressibility, without needing density data for this purpose.
