摘要： Process for preparing 4,4'-diamino-1,1'-dianthraquinonyl pigments by desulphonation of 4,4'-diamino-1,1'-dianthraquinonyl-3,3'-disulphonic acid in sulphuric acid, characterized in that after the desulphonation water is added to the sulphuric acid solution, 4,4'-diamino 1,1'-dianthraquinonyl is isolated as sulphate, the sulphate is hydrolyzed, if necessary by redissolving it in sulphuric acid and adding the solution to water, and the pigment is isolated, if necessary, after treatment with an organic solvent.
摘要翻译：通过在硫酸中脱硫4,4'-二氨基-1,1'-二蒽醌基-3,3'-二磺酸制备4,4'-二氨基-1,1'-二蒽醌基颜料的方法，其特征在于在将脱硫水加入到硫酸溶液中，分离出4,4'-二氨基1,1'-二蒽醌基作为硫酸盐，如果需要，硫酸盐被水解，然后将其溶解在硫酸中，并将溶液加入到水中，颜料如有必要，用有机溶剂处理后分离。
