Abstract
La presente se refiere a un método para preparar/producir 4-aminodifenilamina o sus derivados sustituidos; el método comprende, por un lado, poner en contacto reactivo a una anilina o un derivado anilínico y un nitrobenceno o un derivado de nitrobenceno, y por el otro, hacer que la anilina y el nitrobenceno reaccionen en una zona confinada, en un tiempo y a una temperatura adecuados, en presencia de una mezcla que comprenda una base fuerte y un catalizador de transferencia de fase adecuado, y de un oxidante; el resultado de esa reacción es un producto intermedio de 4-aminodifenilamina. En otro caso, la mezcla puede comprender una sal inorgánica o una sal orgánica metálica, con un catión que sería un catión adecuado de una base inorgánica fuerte, y una base orgánica y oxidante; la mezcla no incluye un producto reactivo de betaína y una base inorgánica fuerte. El producto intermedio de aminodifenilamina se reduce luego para producir 4-aminodifenilamina o sus derivados sustituidos.
