摘要： 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=)nRfn 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-)mRfn, wherein A is a hydroxyl group, a C1-5 alkoxy group, a hydrogen atom, a C1-5 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, Rfn 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 C1-5 alkoxy group or the like, B is a hydrogen atom, and when A is a hydrogen atom, a C1-5 alkyl group or the like, B is the same group as A.

摘要翻译： 为了提供一种制备具有羟基的全氟化合物的方法，因此在还原反应期间不会发生还原反应中间体的聚集，并且可以使用具有-C（= O）OH的全氟化合物作为原料。 在醇溶剂中，在金属氢化物和锂的无机盐存在下还原（AC（= O）= Q =）n R fn，得到（B-CH（OH）-Q-）nm，（AC（= -Q-）m R fn，其中A是羟基，C 1-5烷氧基，氢原子，C 1-5烷基等，Q是全氟亚烷基等，n是至少的整数 1，m为至少为0且小于n的整数，Rfn为n价全氟饱和烃基等，B为取代基的基团，其中A为羟基，C1-5烷氧基或 B为氢原子，当A为氢原子，C 1-5烷基等时，B为与A相同的基团。
