The reaction between hydrazine and oxygen in water

Abstract Studies of the reaction between hydrazine and oxygen at 25° and 70° in alkaline solution have shown that the observed rate is due to catalysis by traces of impurities. It has been found that copper(II) and manganese (II) are the most active catalysts, and, under certain conditions, the copper(II)‐catalysed reaction appears to be homogeneous. Evidence is presented that catalysis occurs by redox reactions. The copper(II)‐catalysed reaction has been studied in some detail, but only the earlier stages fit a simple kinetic equation.
