Abstract: A process for the production of 2,5-diarylamino - 1,4 - benzoquinone - 3,6 - dicarboxylic acids, wherein the two arylamino radicals are identical, comprises treating 2,5-dihydroxyterephthalic acid with an oxidizing agent in presence of a primary aromatic amine unsubstituted in at least one o-position to the amino group. Specified amines are aniline, monochloroanilines, 2,4-dichloroaniline, 2- and 4-nitroaniline, toluidines, anisidines, xylidenes (except 2,6-), 4-aminoazobenzene and 4-aminodiphenylether. Unspecified amines containing other substituents and the naphthalene, anthracene, carbazole, diphenylene oxide and diphenylene sulphide ring systems are also indicated. The products may be cyclized to linear-trans-quinacridonequinones.
