MANUFACTURING METHOD OF FLUORINE-CONTAINING AROMATIC DIAMINE
-
Paragraph 0157-0164, (2020/02/10)
PROBLEM TO BE SOLVED: To provide a production method for obtaining a fluorine-containing aromatic diamine having a hexafluoroisopropanol group(s) (-C(CF3)2OH) bound to an aromatic ring(s) in the aromatic diamine with good selectivity and yield, while suppressing by-production of imines. SOLUTION: There is provided a production method of a fluorine-containing aromatic diamine for obtaining a fluorine-containing aromatic diamine having a hexafluoroisopropanol group(s) bound to an aromatic ring(s), the production method comprising reacting an aromatic diamine and hexafluoroacetone in 1,1,1,3,3,3-hexafluoro-2-propanol. The aromatic diamine and the fluorine-containing aromatic diamine may be both aromatic polycyclic compounds or both aromatic monocyclic compounds. SELECTED DRAWING: None COPYRIGHT: (C)2020,JPO&INPIT
