  A method of producing 4-ADPA is disclosed wherein aniline or substituted aniline derivatives and nitrobenzene are reacted under suitable conditions to produce 4-nitrodiphenylamine or substituted derivatives thereof and/or 4-nitrosodiphenylamine or substituted derivatives thereof and/or their salts, either or both of which are subsequently reduced to produce 4-ADPA or substituted derivatives thereof. The 4-ADPA or substituted derivatives thereof can be reductively alkylated to produce p-phenylenediamine products or substituted derivatives thereof which are useful as antiozonants. A second embodiment of the invention is the tetrasubstituted ammonium salts or alkyl substituted diammonium salts of 4-nitrodiphenylamine, 4-nitrosodiphenylamine and the substituted derivatives thereof wherein each substituent of the tetrasubstituted ammonium ion is independently selected from the group consisting of alkyl, aryl and arylalkyl groups and each alkyl substituent of the alkyl substituted diammonium salt is independently selected.

  本发明公开了一种制备4-ADPA的方法，其中苯胺或取代苯胺衍生物和硝基苯在适当条件下反应，以产生4-硝基二苯胺或其取代衍生物和/或4-亚硝基二苯胺或其取代衍生物和/或它们的盐，其中任一或两者随后被还原以产生4-ADPA或其取代衍生物。 4-ADPA或其取代衍生物可以还原性烷基化以产生对苯二胺产品或其取代衍生物，其可用作抗臭氧剂。 本发明的第二个实施例是4-硝基二苯胺，4-亚硝基二苯胺及其取代衍生物的四取代铵盐或烷基取代的二铵盐，其中四取代铵离子的每个取代基都是独立选择自烷基，芳基和芳基烷基群组，而烷基取代的二铵盐的每个烷基取代基都是独立选择的。
