ABSTRACT:
A process is described for the preparation of perfluorocarboxylic acids by oxidizing perfluoroalkylalkenes with permanganate in aqueous solution, catalytic amounts of at least one quaternary ammonium salt containing alkyl and/or arylalkyl groups being added. It is possible by these means to prepare even perfluorocarboxylic acids having a fairly long chain in a high state of purity in a readily controllable reaction and in a good space-time yield.
