Comprehensive and accurate measurements of the speed of sound in pure propane have been carried out in the liquid and supercritical regions by a double-path-length pulse-echo technique. The measured data cover the temperature range from (240 to 420) K with pressures up to 100 MPa. The measurement uncertainties amount to 3 mK for temperature, 0.01 % for pressures below 10 MPa, and 0.005 % for pressures between 10 MPa and 100 MPa, and 0.02 % for speed of sound. The high accuracy of the measurements is demonstrated by comparisons with literature data and equation of state models.
