This work reports phase equilibrium measurements for the systems CO2(1)+ 1-pentanol(2) and CO2(1)+1-hexanol(2). Experiments were carried out using a high pressure variable-volume view cell with operating temperatures ranged from 303.151 K to 373.15 K and pressures up to 17.05 MPa for the system CO2+1-pentanol, and 303.151 K to 353.151 K with pressures up to 16.2 MPa for the system CO2+1-hexanol. The CO2 molar fractions were ranged from 0.3987 to 0.9192 for the system CO2(1)+1-pentanol(2) and from 0.3926 to 0.9800 for the system CO2(1)+1-hexanol(2), respectively. Only vapor-liquid (VL) phase transitions were observed for the system CO2(1)+ 1-pentanol(2), while for the system with 1-hexanol(2) vapor-liquid (VL), liquid-liquid (LL) and vapor-liquid-liquid (VLL) phase transition were observed. The experimental data sets were modeled using the Peng-Robinson equation of state with a classical van der Waals quadratic mixing rule (PR-vdW2) and with Wong-Sandler (PR-WS) mixing rule, and they were compared with predicted values using the Predictive Soave-Redlich-Kwong (PSRK) equation of state. PR-WS model provided a better fitting to experimental data for both systems modeled. (C) 2014 Published by Elsevier B.V.
