含氟化合物的制造方法
摘要：
本发明提供一种在部分氟化酯的氟化反应中以高收率制造被全氟化的目标物的方法。将使化合物(1)和化合物(2)反应而得的化合物(3)(其中，氟含量在30质量％以上。)在液相中氟化，得到全氟化的化合物(4)。其中，化合物(1)为HOCH2-RA-CH2OH，化合物(2)为X1C(＝O)-C(RB)(RC)(RD)。RA为2价饱和烃基等，不具有醚性氧原子等杂原子。X1为卤素原子，-C(RB)(RC)(RD)为支链状的基团。
摘要（英）：

Provided is a method for producing a desired perfluorinated product with high yield by a fluorination reaction of a partially fluorinated ester. A compound (3), which is produced by reacting a compound (1) with a compound (2) (and which has a fluorine content of 30 mass% or more), is fluorinated in a liquid phase to produce a perfluorinated compound (4), wherein the compound (1) is represented by the formula HOCH2-RA-CH2OH and the compound (2) is represented by the formula X1C(=O)-C(RB)(RC)(RD). RA represents a bivalent saturated hydrocarbon group or the like and does not have a hetero atom such as an ethereal oxygen atom. X1 represents a halogen atom, and -C(RB)(RC)(RD) represents a branched group.
