| 摘要 |
The invention concerns a method for purifying a first fatty acid, particularly a first polyunsaturated fatty acid, based on an initial mixture further comprising at least one second fatty acid and one third fatty acid, the method comprising at least: a first step of liquid-phase chromatographic separation, based on the initial mixture, making it possible to retrieve both a first flow enriched with the first fatty acid and a flow enriched with the second fatty acid; a second step of liquid-phase chromatographic separation, based on the first flow enriched with the first fatty acid, making it possible to retrieve both a second flow enriched with the first fatty acid and a flow enriched with the third fatty acid, the second step of chromatographic separation being carried out in a static-bed chromatographic separation unit. |
