Method for preparing perfluoropolyether carboxylic acid

The invention discloses a method for preparing perfluoropolyether carboxylic acid. The method comprises the steps that (1) perfluoropolyether Rf-COF is used as raw materials to react with alcohol under the existence of fluoride to produce perfluoropolyether ester; (2) the perfluoropolyether ester reacts with basic salt to produce perfluoropolyether carboxylate; (3) the perfluoropolyether carboxylate reacts with concentrated sulfuric acid, then, distillation is performed to obtain the perfluoropolyether carboxylic acid. Compared with the prior art, the method has the advantages that the generation of a great amount of hydrofluoric acid and fluorinions is avoided; the corrosion on equipment is low; the product yield is high; the water content and the fluorinion content in the product are low.
