✦ Synopsis

An account is given of new methods for the electrochemical preparation ofp-aminophenol by the reduction of nitrobenxene. It has been found that control of the electrode potential at a specific value using recently developed potentiostats brings about a marked improvement in the efficiency of the preparation. The effects of the addition of redox compounds to the catholyte and of elevating the temperature of the system are also described in a quantitative way.
