Fluorinated carboxylic acid recovery and reuse

   
   

Fluorinated carboxylic acid, used as a surfactant in fluoropolymerization in aqueous media, can be recovered by scrubbing from the exhaust gas of the dryer during polymer drying and, after concentration and treatment with alumina, directly reused in fluoropolymerization in aqueous media.

Fluorinated carboxylic zuur, dat als capillair-actieve stof in fluoropolymerization in waterige milieu's wordt gebruikt, kan door van het uitlaatgas van de droger te schrobben tijdens polymeer het drogen en, na concentratie en behandeling met alumina worden teruggekregen, direct in fluoropolymerization in waterige milieu's worden opnieuw gebruikt.
