METHOD FOR PRODUCING FLUORINE-CONTAINING ETHER WITH HIGH PURITY

The present invention provides a method for efficiently producing a highly pure fluoroether containing remarkably low concentration of a fluorine-containing alkyl alcohol. The method is suited for scale-up and specifically includes performing countercurrent separation of a crude solution of fluoroether including a fluorine-containing alkyl alcohol as an impurity using water.

METHOD FOR PRODUCING FLUORINE-CONTAINING ALKYL ETHER

A method for producing a fluoroalkyl ether, which comprises reacting a fluoroalkyl alcohol with a fluorinated olefin in the presence of a solvent and a catalyst, wherein the fluoroalkyl alcohol and the fluorinated olefin are continuously supplied into a reactor, a reaction product containing the fluoroalkyl ether is continuously withdrawn from the reactor, and the reaction is carried out while the concentration of the fluoroalkyl alcohol present in the reactor is maintained to be at most 7 mass% based on the total organic component present in the reactor. According to the present invention, a fluoroalkyl ether having a high purity can be produced in an industrial scale and at a high reaction rate.

Chloropolyfluorodiethyl ethers

Fluorination of 2-chlorodiethyl ether by cobalt trifluoride at 110-150 deg C afforded isomers of 2-chloro-pentafluoro-, -hexafluoro-, and -heptafluoro- diethyl ethers.Chlorine was lost in similar fluorinations of 2-chloro-2,2-difluoroethyl ethyl ether, the only products isolated being a hepta- and a hexa-fluoro diethyl ether.Structures were established spectroscopically. - Keywords: Chloropolyfluorodiethyl ethers; Cobalt trifluoride fluorination
