Abstract
 Gibbs ensemble Monte calro simulation were performed to calculate the vapor-liquid coexistence properties for the binary mixtures CO2/CH3OH, CO2/C2H5OH, and CO2/CH3CH2CH2OH. The configuration bias Monte Carlo method was used in the simulation of alcohol. Density of the mixture, composition of the mixture, the pressure-composition diagram, and the radial distribution function were calculated at vapor-liquid equilibrium. The composition and the density of both vapor and liquid from simulation agree considerably well equilibrium. The composition and the density of both vapor and liquid from simulation agree considerably well with the experimental values over a wide range of pressures. The radial distribution functions in the liquid mixtures show that CO2 molecules interact more strongly with methyl group than methylene group of C2H5OH and CH3CH2CH2OH due to the steric effects of the alcohol molecules
