Procedure

The general procedure of Example 8 is repeated except that a solution containing 1.0 M nitric acid and 70 ppm p-aminophenol is charged to the catholyte compartment. A solution of 4 M nitric acid is charged to the anolyte compartment. Concentrated nitric acid is added to the catholyte compartment to maintain the nitric acid concentration between 0.5 M and 1 M under application of an electrical current. While maintaining the temperature between 5° C. and 10° C., a current of 20 amps (5 ASI) and a cell voltage of about 5 volts is applied. A solution of 1.26 M hydroxylammonium nitrate and 0.7 M nitric acid with no detectable ammonium nitrate is obtained from the catholyte compartment. An overall current efficiency of 74% for formation of hydroxylammonium nitrate is achieved.
