    摘要: Mono- and bis-hypofluorites respectively of formula: FO₂S-R f -CF₂OF and FOCF₂-Rʹ f -CF₂OF wherein R f is perfluoroalkylene or perfluorochloroalkylene and Rʹ f is perfluoroalkylene or perfluorooxyalkylene are prepared by a process which is conducted continuously, at a temperature from 0 to 60°C and comprises starting from the respective acyl fluorides
    by reaction of fluorine in the gas phase in the presence of a catalyst consisting of K, Rb, Cs or Ba fluorine, preferably supported on a metal material.

    摘要: The present invention relates to a process for preparing methacrylates of fluorinated alcohols, which comprises reacting said alcohols with an excess of methacrylic acid in the presence of phosphoric anhydride which acts as catalyst and absorbs the water formed. The process may be applied to primary, secondary and tertiary fluorinated alcohols and to alcohols and diols with perfluoroether chains.
