Abstract

1282828 Diarylamines E BILLER 26 Aug 1970 [29 Aug 1969] 41114/70 Heading C2C Diarylamines are produced by condensing an aniline and a phenol in the presence of an organic sulphonic acid, e.g. in the form of an aniline salt, at a temperature of at least 270‹ C., preferably in the range 290-310‹ C. Examples disclose the preparation of diphenylamine, 3- methyl diphenylamine and p-ethyldiphenylamine.
