Title
(EN) METHOD FOR THE MANUFACTURE OF FLUORINATED COMPOUNDS
(FR) PROCÉDÉ DE FABRICATION DE COMPOSÉS FLUORÉS
Abstract
(EN)
A method for the manufacture of perfluorinated compounds is herein disclosed. In particular, the method is useful for the manufacture of perfluorooxyalkyl carboxylic acid salts which can be used as surfactants. The method envisages the fluorination or a fluoroformate of an alcohol comprising a -CH2OCH2-moiety at a temperature equal to or higher than 20°C and allows obtaining high yields and selectivity.
(FR)
L'invention concerne un procédé de fabrication de composés perfluorés. Le procédé est particulièrement utilisé pour la fabrication de sels d'acides carboxyliques de perfluorooxyalkyle qui peuvent être utilisés comme tensioactifs. Le procédé comprend la fluoration d'un fluoroformiate d'un alcool comprenant une fraction -CH2OCH2- à une température égale ou supérieure à 20 °C et permet d'obtenir des rendements élevés et une sélectivité élevée.
