Thermodynamic and acoustic properties of binary mixtures of alcohols and alkanes. I. Speed of sound in (ethanol + n-heptane) under elevated pressures

The speed of sound at atmospheric and elevated pressures (up to over 90 MPa) were measured for (ethanol + n-heptane) mixtures and within the temperature range from (293 to 318) K. The effects of pressure and temperature on the speed of sound have been discussed.
