  The present invention relates to a production method for 4,4′-bis(alkylamino)diphenylamine, and more specifically relates to a method in which 4,4′-dinitrodiphenylamine (4,4′-DNDPA) is produced by reacting urea with nitrobenzene in the presence of a polar organic solvent and a base catalyst, and then the 4,4′-bis(alkylamino)diphenylamine (4,4′-BAADA) is produced by subjecting the 4,4′-DNDPA and a ketone to hydrogenation in the presence of a hydrogenation catalyst.

  本发明涉及一种4,4′-双(烷基氨基)二苯胺的生产方法，更具体地涉及一种方法，其中通过在极性有机溶剂和碱催化剂的存在下，使尿素与硝基苯反应来制备4,4′-二硝基二苯胺（4,4′-DNDPA），然后通过在氢化催化剂的存在下，使4,4′-DNDPA与酮进行氢化反应来制备4,4′-双(烷基氨基)二苯胺（4,4′-BAADA）。
