Usage

General Description

Perfluorooctanoyl fluoride, also known as PFOA, is a synthetic fluorosurfactant and fluorotelomer alcohol used in the production of fluoropolymers such as Teflon. It is a persistent organic pollutant and has been associated with various health risks, including cancer, liver damage, and developmental effects in animals and humans. PFOA is highly soluble in water and does not break down easily in the environment, leading to its widespread contamination of water sources and ecosystems. As a result, many countries and organizations have taken steps to limit or ban the use of PFOA in various consumer products and industrial processes.

EINSTUFIGE HERSTELLUNG HALOGENIERTER CARBONSAUREFLUORIDE AUS DEN FREIEN SAUREN

The reaction of per- or polyhalogenated carboxylic acids with trifluoromethyl or difluorochloromethyl substituted aromatics takes place in the presence of Lewis-acid-catalysts and forms the corresponding acid fluorides in good to very good yields.

PROCESSES FOR PRODUCTION OF FLUORINE-CONTAINING COMPOUNDS

This process for producing fluorine-containing compounds includes liquid-phase fluorination by introducing a raw material compound and fluorine gas into a solvent to replace hydrogen atoms in the raw material compound with fluorine atoms. More specifically, the process for producing fluorine-containing compounds includes (1) promoting fluorination by dissolving the raw material compound in anhydrous hydrofluoric acid and introducing into a liquid-phase fluorination solvent, or (2) promoting fluorination by dissolving the raw material compound in a perfluoro compound having a plurality of polar groups in a molecule thereof and introducing into a liquid-phase fluorination solvent. According to these processes, a fluorination reaction can be carried out at high yield and without containing hardly any isomers while using a hydrocarbon compound as is for the raw material.

1,1,2,2-Tetrafluoroethyl-N,N-dimethylamine: A new selective fluorinating agent

The title compound has been prepared in 96-98% yield by the reaction of tetrafluoroethylene and dimethylamine. 1,1,2,2-Tetrafluoroethyl-N,N-dimethylamine (1) is found to be an effective reagent for the conversion of alcohols into alkyl fluorides. Reaction of 1 and primary alcohols proceeds with high yield formation of the corresponding alkyl fluorides at elevated temperature. However, the reaction of secondary and tertiary alcohols rapidly takes place at 0-10°C, producing corresponding alkyl fluorides as major product along with some olefins.
