METHOD FOR THE MANUFACTURE OF FLUORINATED COMPOUNDS

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 CH.sub.2OCH.sub.2-moiety at a temperature equal to or higher than 20 C. and allows obtaining high yields and selectivity.

METHOD FOR REMOVING PERFLUORINATED ALKANOIC ACIDS

Provided are methods for removing a perfluorinated alkanoic acid from solutions containing the perfluorinated alkanoic acid and a fluorinated alkoxy acid. These methods include contacting the first solution with an anion-exchange resin to produce a second solution and a resultant anion-exchange resin having perfluorinated alkanoic acid adsorbed thereto, wherein the perfluorinated alkanoic acid is present in the first solution at a first concentration and is present in the second solution at a second concentration which is lower than the first concentration, and separating the second solution from the resultant anion-exchange resin.
