A solution was prepared which comprised 206 g diisobutylamine (1.60 mole), 36 g an aqueous solution containing 19.1% by weight NH3 (0.40 mole), 92.6 g acetone (1.60 mole), 41 g acetonitrile (1.00 mole), and 96 g metanol, in which 2.4 g of the disodium salt of ethylenediaminetetracetic acid and 0.4 g ammonium acetate were dissolved. The solution was brought to 50° C, and within the space of half an hour 38.9 g oxygenated water containing 70% by weight H2O2 (0.80 mole) were introduced. The reaction was allowed to continue for seven hours at the same temperature; and the solution was then distilled at 90° C and 20 mm Hg to obtain 26 g acetone N, N-diisobutylhydrazone (0.14 mole, which was 17.5% of the theoretical yield).
