The total vapor pressures of three CO2C6 hydrocarbon systems; CO2benzene, CO2n-hexane, and CO2cyclohexane systems, have been measured at 273.15, 283.15, 298.15 and 303.15 K over the whole composition range by a bubble point method. For the CO2n-hexane system, the densities of the liquid mixtures have also been measured. From the data and the calculated results by the Peng-Robinson equation of state, the activity coefficients of CO2 and the Henry's constants of CO2 in CO2C6 hydrocarbon systems have been obtained. The vapor pressure data have been compared with the results calculated by the Barker's method and by the Peng-Robinson equation of state with the use of four mixing models.
