Abstract:

Compressed liquid densities of 1-pentanol and 2-pentanol have been measured from 313 to 363 K at pressures to 25 MPa. Measurements have been achieved using a vibrating tube densimeter. Water and nitrogen are the reference fluids to calibrate the densimeter. Measurements uncertainties are estimated to be ±0.03 K for temperatures, ±0.008 MPa for pressures and ±0.20 kg·m⁻³ for densities. Two volume-explicit equations with five and six parameters and the 11-parameter BWRS equation of state are used to correlate the experimental densities of 1-pentanol and 2-pentanol reported in this work. Statistical values for the evaluation of the correlations are reported. Comparisons with literature data are performed for the temperature and pressure ranges of the measurements.
