ABSTRACT:
The invention relates to a process for the preparation of perfluorinated carbonyl fluorides of the formula ##STR1## by oligomerization of hexafluoropropene oxide in the presence of a catalyst. The catalyst comprises a mixture of an alkali metal fluoride, a carboxylic acid dinitrile and a polyethylene glycol dimethyl ether.
