General Description

OCTAFLUOROADIPOYL FLUORIDE, also known as 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8-hexadecafluoro-3,5,9,11-tetraoxa-4,10-diphosphadodecane, is a synthetic organic compound primarily used as a reactive intermediate in the production of fluorine-containing polymers such as per- and polyfluoroalkyl substances. It is a fluorinated compound that contains eight fluorine atoms and has a molecular formula of C8F16O2. OCTAFLUOROADIPOYL FLUORIDE is known for its stability, chemical inertness, and low reactivity, making it suitable for various industrial applications, including in the production of non-stick and water-repellent coatings, as well as in the semiconductor and electronics industries. However, its use has raised concerns due to its potential persistence and bioaccumulation in the environment, as well as its association with health and environmental risks.

Preparation method of fluorine-containing binary acyl fluoride

The invention discloses a preparation method of fluorine-containing binary acyl fluoride. Fluorine-containing dicarboxylic acid as a raw material is subjected to fluorination with a fluorination reagent under the action of a solvent and a catalyst to obtain the fluorine-containing binary acyl fluoride. During actual production, the fluorine-containing dicarboxylic acid is directly fluorinated intocorresponding fluorine-containing diacyl fluoride under the action of the organic solvent and the Lewis acid catalyst, and the organic solvent and the specific catalyst are matched with other conditions, so that from the fluorine-containing dicarboxylic acid can be effectively promoted.

PROCESS FOR PRODUCING FLUORINATED COMPOUND

To provide a process for producing a desired perfluorinated product at a high yield in a fluorination reaction of a partially fluorinated ester. A perfluorinated compound (4) is obtained by fluorinating in a liquid phase a compound (3) (wherein the fluorine content is at least 30 mass %) obtained by reacting a compound (1) and a compound (2), wherein the compound (1) is HOCH2—RA—CH2OH, the compound (2) is X1C(═O)—C(RB)(RC)(RD), RA is a bivalent saturated hydrocarbon group or the like which has no hetero atom such as an etheric oxygen atom, X1 is a halogen atom, and —C(RB)(RC)(RD) is a branched group.

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.
