ABSTRACT
Compressed liquid densities of hexan-1-ol and of CO2 (1) + hexan-1-ol (2) binary mixtures (at four different compositions, x1 ) 0.1413, 0.2289, 0.3610, and 0.6673) have been measured from (313 to 363) K and pressures up to 25 MPa. A vibrating-tube densimeter was used to measure the experimental densities. The densities of hexan-1-ol were correlated with a short explicit volume equation and the Benedict-Webb-Rubin-Starling equation of state (BWRS EoS). Excess molar volumes were calculated using density values calculated with the BWRS EoS and the Span-Wagner EoS for hexan-1-ol and CO2, respectively.
