Produktionsmetode:with 1,5-diaminoanthraquinone and 1-chloroanthraquinone as raw materials, the product is obtained through condensation, closed-loop and oxidation.. 72 kg 1,5-diaminoanthraquinone (100%), 168 kg 1-chloroanthraquinone (100%), 71.3 kg sodium carbonate (100%) and 3.6 kg copper powder were put into the condensation pot, heated and dehydrated, reacted at 225-230 ℃ for 2 hours, cooled and crushed, sent into the boiling pot for boiling for 1 hour, filtered while hot, washed to neutral, dried to obtain the condensate. Put 50kg condensate, 150kg aluminum trichloride (industrial product) and 30kg refined salt into the reaction pot, heat to 160-170 ℃ for 1h, put the material into the dilution pot (cold water has been put in advance), generate a large amount of hydrogen chloride gas, absorb it with water, dilute the material, filter it, wash and blow it dry to obtain closed-loop products. Put all the above obtained condensates and 400kg water, 26kg liquid alkali (30%), 1800L sodium hypochlorite solution (effective chlorine content>9 procent) i oxidationsgryden, hæv langsomt temperaturen til 90-95 grad i 1 time, tilsæt vand for at fortynde, tryk på filteret, vask til neutral og føntørre for at opnå farveprodukter.
