Reaktionsschritte

Para-aminodiphenylamine (184 grams, 1.00 mole), 2-undecanone (221 grams, 1.30 moles) and 6.0 grams (dry weight) of carbon supported platinum sulfide catalyst were charged to a one-liter stirred autoclave. The vessel was sealed, pressurized first with nitrogen and then with hydrogen gas, stirred, and heated to 120° C. until the reaction was completed, as indicated by the cessation of hydrogen absorption. The vessel was cooled, vented, and the contents removed. The catalyst was removed by filtration and the water was separated. The excess ketone reactant was removed by heating in vacuo.
