ABSTRACT

The speed of sound u and density for the binary mixture hexane + hexadecane has been measured as a function of composition and temperature along the saturation line between 293.15 K and 373.15 K. The speed of sound was measured by a pulse-phase echo ultrasonic device at a frequency of (1 to 5) MHz with an uncertainty of +-0.1%. The density was measured by an Ostwald-Sprengel-type pycnometer with an uncertainty of +-3 * 10-5 g*cm-3. The experimental results were used to calculate deviations of the speed of sound u, excess molar volume VE, and isentropic compressibility kS. The values u and VE were fitted by the Redlich-Kister equation.
