2,7-Naphthalenedisulfonic acid, 4-amino-3-[2-(4-aminophenyl)diazenyl]-5-hydroxy-6-(2-phenyldiazenyl)-, sodium salt (1:2) Use and Manufacturing
Using p-nitroaniline, H acid and aniline as raw materials, first diazotize p-nitroaniline, couple with H acid for the first time, then diazotize aniline, couple with the aforementioned monoazo compound for the second time , And finally reduce the nitro group with sodium sulfide to obtain the product. The finished product is obtained by salting out, filtering, drying and crushing.
Mainly used for dyeing wool and silk
