Abstract

The density and speed of sound of hexadecane have been measured using two instruments. Both instruments use the vibrating-tube method for measuring density. Ambient pressure (83 kPa) density and speed of sound measurements were carried out with a rapid characterization instrument from 290.65 K to 343.15 K. Adiabatic compressibilities are derived from the density and speed of sound data at ambient pressure. Compressed liquid density measurements were carried out in a second instrument and ranged from 310 K to 470 K with pressures from 1 MPa to 50 MPa. The density measurements are correlated within 0.1 % with a modified Tait equation.
