Title
(EN) RECOVERY OF BRANCHED FLUORINATED EMULSIFIERS
(FR) RÉCUPÉRATION D'ÉMULSIFIANTS FLUORÉS RAMIFIÉS
Abstract
(EN) Described herein is a process for recovering a branched, ether-containing fluorinated emulsifier from an anion exchange resin by (1) contacting the anion exchange resin with a recovery fluid to form an eluate, the recovery fluid comprising an ammonium salt, water, and a water-miscible solvent, wherein the fluorinated emulsifier is of the formula: [Rf-(0-R'f)n-0-CF(CF3)-C(0)0-]i M+1; and (2) separating the anion exchange resin from the eluate.
(FR) L'invention concerne un procédé de récupération d'un émulsifiant fluoré ramifié contenant de l'éther à partir d'une résine d'échange d'anions par (1) mise en contact de la résine d'échange d'anions avec un fluide de récupération pour former un éluat, le fluide de récupération comprenant un sel d'ammonium, de l'eau, et un solvant miscible à l'eau, dans lequel l'émulsifiant fluoré est de formule : [Rf-(0-R'f) n-0-CF(CF3)-C(0)0-]i M+1; et (2) séparation de la résine d'échange d'anions à partir de l'éluat.
