diphenylamine method, where diphenylamine as raw material is nitrosated using a nitrite in an organic solvent to produce N-nitrosodiphenylamine, which is rearranged to 4-nitrosodiphenylamine hydrochloride under the action of anhydrous hydrogen chloride, and then, 4-nitrosodiphenylamine hydrochloride is neutralized with a base to give 4-nitrosodiphenylamine which is finally reduced to 4-aminodiphenylamine by sodium sulfide.
