Direct Black 103 Chemical Properties,Usage,Production

Preparation

3-Aminonaphthalene-1,5-disulfonic acid diazo, and Naphthalen-1-amine coupling, again diazo, and 8-Aminonaphthalene-2-sulfonic acid coupling, product to diazo, in alkaline conditions and 6-Amino-4-hydroxynaphthalene-2-sulfonic acid? coupling.

Properties and Applications

blue grey. To black uniform powder. Soluble in water for violet solution, not soluble in alcohol. The strong sulfuric acid in the green light for gray blue, for purple diluted. The dye solution to join strong hydrochloric acid as dark blue precipitation; Add thick hydrogen oxidation sodium solution blue-purple precipitation. Cellulose fiber of dyeing, the dye absorption rates generally do, in 100 ℃ temperature when the biggest affinity, good levelness. Dyeing copper ions in without the should be, not sensitive to that fights. Mainly used for cotton, viscose, silk and wool/stick blended fabric dyeing and printing.
