摘要 |
The invention is directed to a method of producing one or more 4-aminodiphenylamine intermediates comprising the steps of bringing an aniline or aniline derivative and nitrobenzene into reactive contact and reacting the aniline and nitrobenzene in a confined zone at a suitable time and temperature, in the presence of a mixture comprising an inorganic salt or metal organic salt having a cation that would be a suitable cation of a strong inorganic base, an oxidant and an organic base, the mixture not including a reaction product of betaine and a strong inorganic base.
