The solubility of stearic acid in CO2+acetic acid and CO2+methyl acetate binary mixtures was measured at 318.15 K in the pressure range 90-165 bar and the cosolvent concentration range 0.0-5.1 mol%. The solubility data are discussed qualitatively on the basis of the chemical association principle, which indicates that the larger solubility enhancement by acetic acid is primarily caused by the stronger hydrogen bond between the solute and acetic acid.
