ABSTRACT:
Disclosed is a method of preparing para-aminophenol by the electrolytic reduction of nitrobenzene in an acidic, aqueous reaction medium including a trialkylamine-N-oxide surfactant, such as dimethyldodecylamine-N-oxide, by electrolytic reduction at a cathode comprised of an amalgamated metal, and by electrolytic reduction under essentially anerobic or oxygen-free conditions in the catholyte.
