The density and speed of sound of hexadecane have been measured with two instruments. Both instruments use the vibrating-tube method for measuring density. Ambient pressure (83 kPa) density and speed of sound were measured with a commercial instrument from T = (290.65 to 343.15) K. Adiabatic compressibilities are derived from the density and speed of sound data at ambient pressure. Compressed liquid density was measured in a second instrument and ranged from T = (310 to 470) K with pressures from (1 to 50) MPa. The overall relative expanded uncertainty of the compressed liquid density measurements is (0.10 to 0.13) % (k = 2). The overall relative expanded uncertainty (k = 2.3) of the speed of sound measurements is 0.2 % and that of the ambient pressure density measurements is approximately 0.04 % (k = 2.3). The ambient pressure and compressed liquid density measurements are correlated within 0.1 % with a modified Tait equation.
