Abstract:
1. A method for producing a perfluoro compound having hydroxyl groups, which comprises reducing a compound represented by the following formula (1) in the presence of a metal hydride and an inorganic salt of lithium in an alcohol solvent to obtain a compound represented by the following formula (2): wherein A is a hydroxyl group, a C 1-5 alkoxy group, a C 1-5 fluoroalkoxy group, a hydrogen atom, a C 1-5 alkyl group or a C 1-5 fluoroalkyl group, Q is a perfluoroalkylene group or a perfluoro alkylene group having an etheric oxygen atom between carbon-carbon atoms, n is an integer of at least l, m is an integer at least 0 and less than n, R fn is an n valent perfluoro saturated hydrocarbon group or an n valent perfluoro saturated hydrocarbon group having an etheric oxygen atom between carbon-carbon atoms, and B is a group depending on A wherein when A is a hydroxyl group, a C 1-5 alkoxy group or a C 1-5 fluoroalkoxy group, B is a hydrogen atom, and when A is a hydrogen atom, a C 1-5 alkyl group or a C 1-5 fluoroalkyl group, B is the same group as A.
