Usage

Description

Perfluorononanoic Acid (PFNA) is a fluoroalkanoic acid that is nonanoic acid in which all of the hydrogens in the alkyl chain are replaced by fluorines. It is a white crystalline powder or beige crystals and has the ability to react with bases, oxidizing agents, and reducing agents. Upon decomposition, PFNA can form carbon oxides and hydrogen fluoride.

Uses

1. Environmental Applications:
Perfluorononanoic Acid is used as a persistent environmental pollutant for its high energy C-F bond, which contributes to its persistence in the environment.
2. Health and Safety Applications:
PFNA is used as a toxicant for its potential to interfere with the immune system, liver, development, and endocrine systems in a toxic fashion.
3. Industrial Applications:
Perfluorononanoic Acid is used in various industrial processes due to its chemical properties, such as its ability to react with bases, oxidizing agents, and reducing agents, making it a versatile compound for different applications.

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.
