Separation of unsaturated fatty acid methyl esters was carried out by the membrane extraction with both hydrophilic and hydrophobic membranes in the separation systems of oleic acid methyl ester/linolic acid methyl ester and oleic acid/linolic acid. The hydrophilic and hydrophobic membranes used were hollow fiber types, and polar solution such as acetonitrile with 10wt% water and organic solution such as heptane were fed inside the fiber and in the shell side, respectively. The polar solution containing unsaturated fatty acid methyl esters was fed to the center of the membrane extraction apparatus so that the apparatus had both enriching section and stripping section. By this feed method, the higher membrane performances were obtained than in the case of feeding to the edge of the apparatus. When the hydrophobic and hydrophilic membranes were used in the stripping and enriching sections, respectively, the superior membrane performances were obtained. Further, effects of flow rate of polar solution and the hydrophobic membrane length on the membrane performances were investigated. The membrane performances by this membrane extraction method were analyzed, and the caluculation results were confirmed to be approximately in agreement with the experimental data.

在油酸甲酯/亚油酸甲酯和油酸/亚油酸分离体系中，采用亲水膜和疏水膜对不饱和脂肪酸甲酯进行了分离。所采用的亲疏水膜为中空纤维型，在纤维内部和壳侧分别加注极性溶液（如含10wt%水的乙腈）和有机溶液（如庚烷）。将含不饱和脂肪酸甲酯的极性溶液送入膜萃取装置的中心，使膜萃取装置具有富集段和剥离段。通过这种进料方法，获得了比在装置边缘进料时更高的膜性能。将疏水膜和亲水膜分别用于剥离和富集部分，获得了较好的膜性能。进一步研究了极性溶液流速和疏水膜长度对膜性能的影响。对该方法提取的膜性能进行了分析，计算结果与实验数据基本吻合。
