Abstract

The sound velocity in liquid ethanol has been measured up to 280 MPa and at temperatures between 193 and 263 K, using a phase-comparison, pulse-echo technique operating at 2 MHz. The density, isothermal compressibility, isobaric thermal expansion coefficient, and specific heat have been evaluated from the measured speed of sound starting from the density and specific heat data at 0.1 MPa and making use of a modified computational method originally developed by Davis and Gordon. The derived density data have been used to examine the validity of several empirical equations of state.
