Solubilities are measured for natural tocopherols and fatty acid methyl esters(FAMEs) under partly isothermal, isobaric and isochoric conditions in the range of temperature of 40-60deg.C and pressure of 9.7-16.2MPa based on soybean de-odorizer(DOD) pretreatment, the separation factors between FAMEs and tocopherols are 3.1-5.4 in this study. Furthermore, three different technology projects are analyzed qualitatively and quantitatively of single column extraction (SCE), extraction and fractionation (EF), two-column extraction (TCE).
