Abstract

A process for preparing N-aliphatic substituted p-phenylenediamine intermediates comprising: (a) contacting an aliphatic amine or substituted aliphatic amine derivative and nitrobenzene in the presence of a suitable solvent system, and (b) 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.
