| titleOfInvention | Process for producing phenylenediamine derivatives |
| abstract | [PROBLEMS] To produce a phenylenediamine derivative by reacting N, N'-diphenyl-1,4-phenylenediamine with a styrene derivative, and most of the reaction products are disubstituted or polysubstituted styrene derivatives. And a method for producing a phenylenediamine derivative that is effectively used as an antioxidant that contains almost no mono-substituted product and is virtually free from volatilization and heat denaturation even under high temperature conditions exceeding 150 ° C. provide. SOLUTION: N, N′-diphenyl-1,4-phenylenediamine and general formula (Wherein R 1 and R 2 are each a hydrogen atom, a lower alkyl group or a lower alkoxyl group, and R 3 and R 5 are each a hydrogen atom or a methyl group) and a styrene derivative represented by Reaction in the presence of the general formula Wherein R 1 , R 2 and R 3 are as defined above, R 4 is a methyl group or an ethyl group, and n and m are 1, 2 or 3. To manufacture. [Selection figure] None |
