The synthetic method was applied to measure the phase equilibrium of binary mixtures involving CO2 and the following alcohols: undecan-2-ol, undecan-6-ol, undec-10-en-1-ol, and 2-methylpentan-2,4-diol. Measurements were performed at three different temperatures: 313.15, 323.15, and 333.15 K. The bubble points were measured at carbon dioxide mole fractions between 0.1 and 0.8 and at a pressure range of 13-160 bar. The results were correlated with the Peng-Robinson equation of state using the quadratic mixing rules. (C) 2003 Elsevier B.V. All rights reserved.
