Abstract
A fluorine-containing ether monocarboxylic acid aminoalkyl ester represented by the general formula:CFO[CF(CF)CFO]CF(CF)COO(CH)NRR(wherein Ris a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, an aryl group, or an aralkyl group, preferably an alkyl group having 1 to 6 carbon atoms or an aryl group; Ris an alkyl group having 1 to 12 carbon atoms, an aryl group, or an aralkyl group, preferably an alkyl group having 1 to 6 carbon atoms or an aryl group; n is an integer of 1 to 3; a is an integer of 2 to 20, preferably an integer of 4 to 10; and b is an integer of 1 to 12, preferably an integer of 1 to 3). Such a fluorine-containing ether monocarboxylic acid ester having an amino group at the end of the ester group is produced by reacting a perfluoroether carboxylic acid fluoride compound CFO[CF(CF)CFO]CF(CF)COF and a hydroxyalkyl amine compound HO(CH)NRRin the presence of an alkali metal fluoride.
