Usage

General Description

Potassium perfluorohexanoate is a chemical compound that belongs to the group of perfluorocarboxylates, which are perfluorinated compounds with a carboxylate functional group. It is commonly used as a surfactant in various industrial applications, including in the production of fluoropolymer coatings, adhesives, and lubricants. Potassium perfluorohexanoate is known for its high stability and resistance to heat, chemicals, and solvents, making it a valuable ingredient in the formulation of products that require durable, non-stick, and water-repellent properties. However, due to concerns about its persistence and potential environmental and human health impacts, it is being closely monitored and regulated in some regions.

Production process of fluorine-containing carboxylic acid

The invention discloses a production process of fluorine-containing carboxylic acid. The method comprises the following steps: by taking fluorine-containing olefin as a raw material, carrying out an oxidation reaction to obtain fluorine-containing carboxylate, reacting the fluorine-containing carboxylate with an acylating chlorination reagent to obtain a corresponding mixture of fluorine-containing acyl chloride and fluorine-containing acid anhydride, and hydrolyzing and drying the mixture of fluorine-containing acyl chloride and fluorine-containing acid anhydride to prepare the 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 extraction process, and is simpler, more convenient and more applicable; the purity of the fluorine-containing carboxylic acid prepared by the method can reach 98% or above.
