摘要
A series of bisceramidonines has been synthesized by sulphuric acid (70%) cyclization of N, N prime -bisanthraquinonyl-arylenediamines. The latter compounds were synthesized by the Ullman condensations of 1-nitroanthraquinone and 1-amino-4-chloroanthraquinone with o-, m-, p-phenylenediamines and benzidine and its derivatives. The dyeing properties of bisceramidonines as disperse dyes were tested. Ceramidonines prepared by sulphuric acid cyclization of 1-arylaminoanthraquinones were quanternized with dimethylsulphate to obtain cationic dyes. The dyeing properties of the cationic dyes were tested on acrylic fiber.
