High pressure density behaviors for fluid mixtures made of carbon dioxide with solvent, methyl acetate, ethyl acetate, 2-propyl acetate, methanol, 1-propanol, or 2-propanol, at 313.15 K were satisfactorily correlated. The standard deviations were between 0.4 and 2.2 kg m -3 in density for each system in the composition range from 0.00 to 0.95 mole fraction of carbon dioxide.
