<p>To provide a method for producing a perfluoro compound having hydroxyl groups, whereby agglomeration of a reduction reaction intermediate tends not to occur during a reduction reaction, and a perfluoro compound having -C(=O)OH can be used as a starting material. Reducing (A-C(=O)=Q=) n R fn in the presence of a metal hydride and an inorganic salt of lithium in an alcohol solvent to obtain
(B-CH(OH)-Q-) n-m (A-C(=O)-Q-) m R fn , wherein A is a hydroxyl group, a C 1-5 alkoxy group, a hydrogen atom, a C 1-5 alkyl group or the like, Q is a perfluoroalkylene group or the like, n is an integer of at least 1, m is an integer at least 0 and less than n, R fn is an n valent perfluoro saturated hydrocarbon group or the like, and B is a group depending on A wherein when A is a hydroxyl group, a C 1-5 alkoxy group or the like, B is a hydrogen atom, and when A is a hydrogen atom, a C 1-5 alkyl group or the like, B is the same group as A.</p> |
