| Abstract: | The mechanisms of the formation of impurities in the preparation of p-aminophenol by catalytic or electrolytic reduction of nitrobenzene were discussed. The methods for suppressing the formation of impurities and eliminating them afterward were proposed. The quality of p-aminophenol prepared by this methods met the specification of medicine. |
