The purpose is to economically obtain highly unsaturated fatty acid derivatives of high purity and good quality. Provided is a method for acquiring highly unsaturated fatty acid derivatives by bringing a mixture of fatty acid derivatives into contact with an aqueous silver salt solution, with the free fatty acid content in the aqueous silver salt solution being less than 0.2 meq per 1 g silver when the method is performed using the aqueous silver salt solution repeatedly.
L'objectif de l'invention est d'obtenir par un procédé économique des dérivés d'acides gras hautement insaturés de pureté élevée et de bonne qualité. A cette fin, l'invention propose un procédé d'obtention de dérivés d'acides gras hautement insaturés qui consiste à mettre un mélange de dérivés d'acides gras en contact avec une solution aqueuse de sel d'argent, la teneur en acides gras libres de la solution aqueuse de sel d'argent étant inférieure à 0,2 meq par gramme d'argent lorsque le procédé est mis en uvre en utilisant la solution aqueuse de sel d'argent à plusieurs reprises.
