    摘要: A process of producing a perfluorocarboxylic acid fluoride having the formula (1): ##STR1## wherein n is an integer of at least 2, comprising effecting oligomerization of hexafluoropropylene oxide in the presence of an alkali metal fluoride a sulfone or a mixture of a sulfone with an ether having the formula (2):CH.sub.3 O(CH.sub.2 CH.sub.2 O).sub.m CH.sub.3 (2)where m is an integer of 2 to 6. This process makes it possible to improve production yield of hexafluoropropylene oxide oligomers remarkably, and to raise a reaction temperature for the oligomerization, as compared with conventional methods, thereby shortening reaction time therefor.
