Method for separating and removing aminobiphenyl from diphenylamine |
| abstract |
(57) An object of the present invention is to provide a simple and effective method for removing aminobiphenyl (ABP) from diphenylamine (DPA). SOLUTION: DPA to be purified is treated at elevated temperature with a substance in which oxygen is bound to a C atom, N atom or another O atom by a double bond, and then the treated mixture. By separating and removing DPA from APA, ABP is separated and removed from DPA. |
