Beschreibung
Zusammenfassung:	The invention relates to a process for the removal of bromide from aqueous solutions to produce brominated oils, comprising: combining in a reaction vessel bromide-containing aqueous solution and one or more unsaturated compounds selected from the group consisting of unsaturated fatty acids, esters of unsaturated fatty acids and mixtures thereof; oxidizing the bromide in an acidic environment to generate elemental bromine, wherein the bromine adds to the carbon- carbon double bonds of said unsaturated compound(s); and separating the reaction mixture to bromide-depleted aqueous phase and brominated oily phase. L'invention concerne un procédé d'élimination de bromure de solutions aqueuses pour produire des huiles bromées, comprenant : la combinaison dans cuve de réaction d'une solution aqueuse contenant du bromure et d'un ou plusieurs composés insaturés sélectionnés dans le groupe constitué d'acides gras insaturés, d'esters d'acides gras insaturés et de mélanges de ceux-ci ; l'oxydation du bromure dans un environnement acide pour générer du brome élémentaire, le brome ajoutant aux doubles liaisons carbone-carbone dudit (desdits) composé(s) insaturé(s) ; et la séparation du mélange réactionnel en phase aqueuse appauvrie en bromure et en phase huileuse bromée.
