N2 - Vapour-liquid equilibrium of CO2+[0.00871 glycerol+0.99129 (ethanol or 1-propanol or 1-butanol)] mixtures was measured at the temperatures of 313.15K and 333.15K, and close to the critical line, at pressures up to 12MPa. On the liquid side, the bubble points measured for these ternary mixtures follow closely the behaviour of VLE reported by several authors for the corresponding binary mixtures without glycerol. On the vapour side, however, dew points for the ternary mixtures deviate significantly from VLE results for the binaries. A correlation of the results obtained for the CO2+glycerol+ethanol mixture with the Peng-Robinson equation of state, admitting quasi-binary behaviour, equally yields good agreement on the liquid side, and significant deviations on the vapour side.
