Usage

General Description

2-(Fluorosulfonyl)Difluoroacetyl Fluoride is a chemical compound consisting of fluorine, sulfur, and acetyl groups. It is classified as an organofluorine compound, due to the presence of carbon-fluorine bonds, one of the strongest bonds in organic chemistry. Its synthesis involves applying fluorination methods on its precursors, which can be a complex process due to the high reactivity of fluorine. The properties and specific uses of this particular chemical are not widely documented, suggesting it may pertain to specialized fields in chemistry or may be used in further complex chemical reactions. Given the reactivity of fluorine and sulfur, handling of this compound necessitates rigorous safety measures.

Improvement of procedures for preparing Tetrafluoroethane-β-sultone and fluorocarbonyldifluoromethanesulfonyl fluoride

Synthesis of tetrafluoroethane-β-sultone by the reaction of tetrafluoroethylene with sulfuric anhydride and of fluorocarbonyldifluoromethanesulfonyl fluoride by catalytic reaction of tetrafluoroethylene with sulfuric anhydride using BAU-2, SKT-6, or AG-3 activated carbon as catalyst was studied. The possibility of replacing sulfuric anhydride prepared by distillation from oleum by sulfuric anhydride prepared by sulfur dioxide oxidation was demonstrated.

PROCESS FOR THE PRODUCTION OF WATER-SOLUBLE FLUORINE -CONTAINING VINYL ETHERS

The present invention relates to a method for producing a water-soluble fluorine-containing vinyl ether which comprises subjecting a fluorine-containing 2-alkoxypropionic acid derivative represented by the following general formula (I): (wherein A represents -OM1 or -OM21/2, and M1 represents an alkali metal and M2 represents an alkaline earth metal; X represents a halogen atom; Y1 and Y2 are the same or different and each represents a fluorine atom, a chlorine atom, a perfluoroalkyl group or a fluorochloroalkyl group; n represents an integer of 0 to 3, and n of Y1s may be the same or different; m represents an integer of 1 to 5, and m of Y2s are the same or different; and Z represents a hydrophilic group) to thermal decomposition at a temperature of not lower than 50°C but lower than 170°C in the presence of a coordinating organic solvent to give a water-soluble fluorine-containing vinyl ether represented by the general formula (II): (wherein Y1, Y2, Z, n and m are as defined above),???said coordinating organic solvent having a coordinating property with an ion of said M1 or an ion of said M2???said coordinating organic solvent being in an amount of 10 to 1,000 parts by mass per 100 parts by mass of the fluorine-containing 2-alkoxypropionic acid derivative.

Fluorinated olefins and oleum

Oleum has some advantages over pure sulfur trioxide and may be successfully used for preparation of beta-sultones from hexafluoropropene, 2H-pentafluoropropene, 6H-perfluoro-1-hexene and perfluoro(propylvinyl) ether (VE). Depending on the reaction conditi
