    摘要： Object of the invention is a process for the production of 4-nitroso diphenylamine wherein N-nitroso diphenylamine is rearranged in the presence of an alcoholic hydrogen chloride solution by selecting the reaction conditions in such a way that the hydrochloride of 4-nitroso diphenylamine remains dissolved in the reaction medium. In this way spontaneous, uncontrollable decompositions do not occur.
