Abstract:
A bis(perfluoroether carboxylic acid alkyl)amino ester represented by the general formula: {CnF2n+1O[CF(CF3)CF2O]aCF(CF3)COO(CH2)b}2NR, wherein R is 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; n is an integer of 1 to 3; a is an integer of 0 to 20, preferably an integer of 1 to 6; and b is an integer of 1 to 12, preferably an integer of 1 to 4. The bis(perfluoroether carboxylic acid alkyl)amino ester having an amino group at the end of the ester group is produced by reacting a perfluoroether carboxylic acid fluoride compound of the formula: CnF2n+1O[CF(CF3)CF2O]aCF(CF3)COF and a bis(hydroxyalkyl)amine compound of the formula: HO(CH2)bNR(CH2)bOH at a molar ratio of 2:1 in the presence of an alkali metal fluoride.
