benzo[h]benz[5,6]acridino[2,1,9,8-klmna]acridine-8,16-dione - Reference Information
| color index | 70600 |
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | reduced yellow g is mainly used for dyeing and printing of cotton, dimension, dimension/cotton, polyester/cotton. It has good affinity for cotton fiber and good levelness. Because it is difficult to oxidize, hydrogen peroxide or sodium perborate is used for oxidation to obtain bright color. It is also used to make organic pigments. |
| production method | using 1-chloro-2-acetylaminoanthraquinone as raw material, dechlorination and condensation reactions are completed in DMF medium with copper powder as catalyst. after copper removal, the product is hydrolyzed and closed-loop in the presence of concentrated sulfuric acid.. |
