Uses

Used in Pharmaceutical Industry:
Perfluorononanoyl chloride is used as a chemical intermediate for incorporating nonafluorobutyl groups into organic compounds, which is essential in the synthesis of certain pharmaceuticals. This modification can enhance the properties of the resulting drugs, such as solubility, stability, and bioavailability.
Used in Pesticide Industry:
In the pesticide industry, perfluorononanoyl chloride is used as a key component in the production of certain pesticides. The introduction of nonafluorobutyl groups can improve the effectiveness and selectivity of these pesticides, making them more efficient in controlling pests and reducing environmental impact.
Used in Surfactant Industry:
Perfluorononanoyl chloride is used as a raw material in the synthesis of surfactants, which are essential in various applications such as detergents, wetting agents, and emulsifiers. The incorporation of nonafluorobutyl groups can enhance the surfactant's performance, providing better stability and improved interfacial properties.
Used in Fire Control Agents Industry:
In the fire control agents industry, perfluorononanoyl chloride is used as a component in the production of fire-fighting foams and other fire suppression products. The nonafluorobutyl groups contribute to the formation of a stable and effective barrier that helps to extinguish fires and protect valuable assets.

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.

Multiple pathways in cyclodextrin-catalyzed hydrolysis of perfluoroalkylamides

The hydrolysis of p-nitroanilide of perfluoroalkanoic acids, CF3(CF2)nCO-, with n = 1, 2, 3, 5, 6, and 7, 1a-f, was studied in the presence of β-cyclodextrin (CD). All reactions were catalyzed by CD through the formation of a 1:1 and 1:2 inclusion complexes. The association equilibrium constants for the 1:1 complexes were dependent on the number of carbons of the fluoroalkyl chain, whereas those of the 1:2 complexes were almost independent. These results indicate that, in the former case, the perfluoroalkyl chain is included, while in the latter, the CD unit encloses the aryl ring. For compounds 1a,b both complexes were more reactive than the substrate itself. The ratio of the reaction of complexed to uncomplexed substrate had its highest value for 1a in the case of the 1:1 complex, and for 1b, the 1:2 complex. This is attributed to the geometry of the complexes. Although compounds 1c-e reacted at the same rates in the free or 1:1 complexed form, CD accelerated the reactions because of an increase of the pKa of the substrate, which results in a higher concentration of the neutral reactive substrate at the same pH. Compound 1f formed aggregates even at 10-6 M concentration, and CD-induced deaggregation resulted in catalysis of the reaction.
