Process for preparing n-aliphatic substituted p-phenylenediamines |
| abstract |
A process for preparing N-aliphatic substituted p-phenylenediamine intermediates is provided which comprises contacting an aliphatic amine or substituted aliphatic amine derivative and nitrobenzene in the presence of a suitable solvent system, and reacting the aliphatic amine or substituted aliphatic amine derivative and nitrobenzene in the presence of a suitable base and a controlled amount of protic material at a suitable temperature in a confined reaction zone. In one embodiment, the N-aliphatic substituted p-phenylenediamine intermediates are reduced to N-aliphatic substituted p-phenylenediamines and the N-aliphatic substituted p-phenylenediamines can be reductively alkylated to N'-alkylated, N-aliphatic substituted p-phenylenediamines. In another embodiment of the invention, N-aliphatic substituted p-phenylenediamine intermediates are reductively alkylated to N'-alkylated, N-aliphatic substituted p-phenylenediamines. |
