✦ Synopsis

Experimental phase equilibria for the ternary system consisting of supercritical carbon dioxide (SC-CO?) + methyl oleate + oleic acid were measured at 3 13.15 and 333.15 K and pressures up to 35 MPa. The equilibrium data were correlated using the Peng-Robinson equation-of-state with the Panagiotopoulos and Reid mixing rules. The solubilities and distribution coefficients of methyl oleate and oleic acid in SC-CO2 were studied at different extraction conditions and mole fraction ratios of methyl oleate to oleic acid.
