FLUORINATED ETHER ALCOHOL AND PROCESS FOR PRODUCTION THEREOF

摘要

A novel fluorine-containing ether alcohol having a terminal perfluoromethoxy group represented by the following general formula :
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒCF 3 O[CF(CF 3 )CF 2 O] n CF(CF 3 )CH 2 OH
(where n is an integer of 0-12) can be produced by reduction reaction of a fluorine-containing ether carboxylic acid alkyl ester represented by the following general formula :
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒCF 3 O[CF(CF 3 )CF 2 O] n CF(CF 3 )COOR
(where R is an alkyl group, and n is an integer of 0-12), and the fluorine-containing ether alcohol alone or as a mixture with a fluorine-containing ether alcohol having a terminal perfluoroethoxy group or a terminal perfluoropropoxy group is expected to show a peculiar surfactant characteristic owing to the peculiarity of reaction at the terminal position, and can be used as a dispersing agent or a levelling agent.
