The speed of sound in 2-ethyl-1-hexanol has been measured in the temperature range from (293.15 to 318.15) K at pressures up to 101 MPa by the pulse-echo-overlap method. The density has been measured in the temperature range from (278.15 to 363.15) K under atmospheric pressure with a vibrating tube densimeter. These experimental results are then used to calculate the densities, isobaric and isochoric heat capacities, isobaric coefficients of thermal expansion, and isentropic and isothermal compressibilities, as well as the internal pressure and ratio of heat capacities as a function of temperature and pressure. The effects of pressure and temperature on these properties are discussed. Densities are correlated with a Tait equation.
