| Use | 4-[(4-aminophenyl) azo]-1-Naphthylamine is also called dispersed diazo black GNN. 4-[(4-aminophenyl) azo]-1-Naphthylamine dispersed diazo black GNN is mainly used for dyeing polyester and its blended fabric, and also used for dyeing acetate fiber, triacetate fiber and nylon. Dyeing should be used with the use of phenol AS-D, after dyeing in acidic medium with sodium nitrite diazotization color processing, can be black. |
| production method | using p-nitroaniline and 1-Naphthylamine as raw materials, P-nitroaniline was diazotized first, and then coupled with 1-Naphthylamine, the product was then reduced with sodium sulfide. The final product was obtained by filtration and drying. |
