Procedure

The general procedure of Example 8 is repeated except that tetrabutylammonium chloride is added into the catholyte compartment. A solution of 1 M nitric acid, 50 mM 1,4-phenylenediamine and 0.1 M tetrabutylammonium chloride is charged to the catholyte compartment. A solution of 4 M nitric acid is charged to the anolyte compartment. 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 45 amps (3 ASI) and a cell voltage of about 6.5 volts is applied. The catholyte is stirred under application of the current. A solution of 1.65 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 85% for formation of hydroxylammonium nitrate is achieved.
