A process for bis (4-aminophenyl) hexafluoropropane
摘要:
This invention is an improved process for preparing 2,2-bis(4-aminophenyl)hexafluoropropane which comprises subjecting 2,2-bis(4-aminocarbonylphenyl)hexafluoropropane to the Hofmann reaction and then treating that reaction product under reducing conditions to produce the desired amine in high yield.
