Experimental speeds of sound and densities are presented for the liquid phase of 1-chlorohexane. The measurements were carried out along seven isotherms from (293.15 to 413.15) K at pressures from saturation up to 200 MPa. The speed of sound was measured by a pulse-phase echo ultrasonic device at a frequency of (1 and 5) MHz with an uncertainty of 0.2 %. The density was measured by an acoustic piezometer with an uncertainty of +/- 0.3%. The experimental results have been used to calculate isentropic compressibility (k(S)) with an uncertainty of +/- 1%. The temperature and pressure variation of sound speed, density, and isentropic compressibility are discussed. The experimental results were used to calculate various thermophysical properties such as isobaric thermal expansion coefficient (alpha(P)), isothermal compressibility (k(T)), temperature coefficient of pressure at constant volume ((phi P/phi T)(V)) and internal pressure (P-i).
