Abstract

The invention relates to a process for the preparation of industrially useful fluorine compounds such as acyl fluorides, that is, a process which comprises reacting a compound of the following general formula: RAHOCH(CH¿3?)CH2OCOCF(CF3)OR?Bf¿ having a fluorine content of 30 % by mass or above with fluorine in a liquid phase to thereby obtain a compound of the following general formula: RAfOCF(CF¿3?)CF2OCOCF(CF3)OR?Bf¿, and subjecting this compound to ester linkage cleavage (wherein RAH is C¿1-20? alkyl or C1-20 alkyl containing one or more etheric oxygen atoms; R?Af¿ is a group derived from RAH by perfluorination; and RBf is C¿1-20? perfluoroalkyl or C1-20 perfluoroalkyl containing one or more etheric oxygen atoms).
