Title:
含フッ素ポリエーテルカルボン酸アミドの製造法
Document Type and Number:
Japanese Patent JP5381273
Kind Code:
B2
Abstract:
A fluorine-containing polyether carboxylic acid amide represented by the general formula: C n F 2n+1 O(C 3 F 6 O) m RfCONHAr, wherein Rf is a fluorocarbon group having 1 to 2 carbon atoms, Ar is a nitrogen-containing heterocyclic group, n is an integer of 1 to 3, and m is an integer of 10 to 30, is produced by reacting a fluorine-containing polyether carboxylic acid fluoride represented by the general formula: C n F 2n+1 O(C 3 F 6 O) m RfCOF, wherein Rf, n, and m are as defined above, with a nitrogen-containing heterocyclic amine compound represented by the general formula: ArNH 2 , wherein Ar is as defined above; wherein the reaction is carried out while a reaction temperature is first increased to 80 to 100°C, and then increased at a temperature increase rate that produces a temperature difference of 3 to 5°C after 48 hours.
