Tris-perfluoro-alkyl phosphine oxides prepn. - by electrochemical fluorination of trialkyl phosphine oxides, use as solvents, complexants, etc

The novel-tris-(perfluoroalkyl)-phosphine oxides are of formula (I) (RF)3P=O (I) (where RF is opt. branched 2-8C perfluoroalkyl). E.g. Tripopyl phosphine oxide is electrochemically fluorinated in anhydrous HF to give perfluoropropylphosphine oxide. As solvents for rare earth metal salts; complexants...

Beschreibung
Zusammenfassung:The novel-tris-(perfluoroalkyl)-phosphine oxides are of formula (I) (RF)3P=O (I) (where RF is opt. branched 2-8C perfluoroalkyl). E.g. Tripopyl phosphine oxide is electrochemically fluorinated in anhydrous HF to give perfluoropropylphosphine oxide. As solvents for rare earth metal salts; complexants in the sepn. of useful heavy metals in non-aqs. media; as oleohydrophobic substances in the prepn. of flame-repellant compsns., raw materials for the prepn. of surfactants. L'invention concerne la chimie. Les produits faisant l'objet de l'invention sont des produits nouveaux caractérisés en ce qu'ils consistent en des oxydes de tris-(perfluoralcoyl)-phosphines de formule générale :
