Process for the preparation of nitrodiphenylamines

   
   

The present invention relates to a process for the preparation of nitrodiphenylamines by reaction of nitrohalogens with anilines, a base and a catalyst, and to a process for the preparation of aminodiphenylamine by hydrogenation of the nitrodiphenylamine intermediately prepared.

Присытствыющий вымысел относит к процессу для подготовки nitrodiphenylamines реакцией nitrohalogens с анилинами, основанием и катализатором, и к процессу для подготовки aminodiphenylamine гидрогенизацией промежуточно подготовленного nitrodiphenylamine.
