| 摘 要： | 在２５℃、４０℃和５０℃下，测定了含二十碳五烯酸（ＥＰＡ）和二十二碳六烯酸（ＤＨＡ）共７７．５９％的鱼油乙酯在超亚临界二氧化碳中的溶解度，并得到了相应条件下的ＥＰＡ和ＤＨＡ的分离度。用ＰＲ和ＳＲＫ方程对所测溶解度数据进行了关联。

| Abstract: | The solubilities of fatty acids ethy1 esters containing 77 9% eicosapentaenoic acid (EPA)and docosahexaenoic acid (DHA)in CO 2 ranging from 6 MPa to 16 MPa at 298 15 K,313 15 K and 323 15 K were determined,and correlated by using PR and SRK EOS.The average separation coefficients for EPA and DHA at the same conditions are 1 138,1 433 and 1 397 respectively. |
