General Description

PERFLUORO(2-METHYL-3-OXAHEXANOIC) ACID (PMOA) is a perfluorinated carboxylic acid compound with a chemical formula C7H3F13O3. It is a synthetic compound that is part of a group of chemicals known as per- and polyfluoroalkyl substances (PFAS). PMOA is used in the manufacturing of various products such as non-stick coatings, stain-resistant fabrics, and firefighting foams. However, it has been found to be persistent in the environment and is a suspected human carcinogen. It has been detected in the environment and in biota, posing a potential risk to human health and the environment. Due to its harmful effects, there is increasing concern and regulatory scrutiny over the use and disposal of PMOA and other PFAS compounds.

Preparation method of fluorine-containing carboxylic acid

The invention discloses a preparation method of fluorine-containing carboxylic acid. The method comprises the following steps: reacting fluorine-containing carboxylate used as a raw material with an acylating chlorination reagent to obtain a corresponding mixture of fluorine-containing acyl chloride and fluorine-containing anhydride, and hydrolyzing and drying the mixture of fluorine-containing acyl chloride and fluorine-containing anhydride to obtain high-purity fluorine-containing carboxylic acid. The method provided by the invention is suitable for post-treatment of fluorine-containing carboxylic acid prepared by a fluorine-containing olefin (monoolefine, diene, cycloolefin and the like) oxidation method, replaces the traditional strong acid acidification and ether continuous extractionprocess, and is simpler, more convenient and more applicable; and the method can also be used for recovering and purifying a fluorine-containing carboxylate emulsifier. The purity of the fluorine-containing carboxylic acid prepared by the method can reach 98% or above.

METHODS FOR CONVERTING FLUORINATED COMPOUNDS

Methods of converting a fluorinated compound into a fluorinated acyl fluoride or derivative thereof, the method including reacting the fluorinated compound with a catalytic amount of at least one transition metal compound and an oxygen-containing compound to form the fluorinated acyl fluoride or derivative thereof. Compounds formed using such methods are also included, including for example and derivatives thereof, or combinations thereof.

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.
