Abstract: The method of catalytic transfer hydrogenation is applied. F~(3+) is used as catalyst, hydrazine hydrate as hydrogen donor, 3,3'-dinitro-4,4'-diaminodiphenylether as hydrogen acceptor and methanol as solvent respectively. The reaction gives satisfactory results, as the yield of 3, 3', 4,4'-tetraminodiphenylether amount to 80% and the product have good qualities. Some relevant factors have also been discussed, namely, temperature, time, amounts of hydrazine hydrate, catalyst and solvent used, concentration of hydrazine hydrate, recycling use of catalyst and the optimal working conditions. Since the method has so many advantages, such as simpler equipments, shorter reaction time, high yield, safety, easiness of operation, and low cost of catalyst, so it possesses high potentiality of being used industrially.
