摘要 |
A process for efficiently producing an acyl fluoride and a carboxylic acid salt while inhibiting side reactions. R<A>ÄOCH(CH3)CH2ÜnOH (1) and XCOR<B> (R<A> and R<B> each is a group which upon fluorination becomes a perfluoroalkyl group, X is a halogen atom, and n is an integer of from 1 to 10) (2) are reacted to form an ester compound (3); the compound (3) is fluorinated in a liquid phase; and the ester bond of the fluorinated compound (4) is cleaved to obtain a perfluoroacyl fluoride (5). Further, this perfluoroacyl fluoride (5) is hydrolyzed and then reacted with ammonia or an alkali metal hydroxide to obtain a carboxylic acid salt (7). |
