Title (EN) PROCESS FOR SEPARATING FLUORINE-CONTAINING SURFACTANT
(FR) PROCEDE DE SEPARATION DE TENSIOACTIF CONTENANT DU FLUOR
Abstract: front page image
(EN)In a process for separating a fluorine-containing surfactant, the first aqueous phase comprising the fluorine-containing surfactant and water and having a first pH value is contacted with the first organic phase comprising an organic compound which is immiscible in water so as to move the fluorine-containing surfactant from the first aqueous phase to the first organic phase, and thereby the second aqueous phase having a lowered concentration of the fluorine-containing surfactant and the second organic phase containing the moved fluorine-containing surfactant are obtained.
(FR)L'invention concerne un procédé de séparation de tensioactif contenant du fluor par contact entre la première phase aqueuse renfermant ledit tensioactif et de l'eau et ayant un premier pH avec la première phase organique renfermant un composé organique non miscible avec l'eau, de manière à déplacer ledit tensioactif de la première phase aqueuse vers la première phase organique. Ainsi, on établit la seconde phase aqueuse à concentration inférieure de tensioactif contenant du fluor et la seconde phase organique contenant ledit tensioactif déplacé.
