    摘要: Dimers of diarylamines are prepared by a process comprising treating a diarylamine-perchlorate salt with an oxidizing agent in an acidic medium. Exemplary of the products obtained is 4,4''dianilino-1,1''-binaphthyl, which is made by treating N-phenylAlpha -naphthylamine-perchlorate with chromium trioxide in acetic acid and water. The products thus produced are useful antioxidants in lubricants.
