azoic coupling component;Naphthol
Molecular formula :
MW :
CAS :

nature : commonly known as homework properly (Naphthol), bottoming agent. Referring to the azo dye coupling components. When grounding as dyeing agent, and color-diazonium salt in the cellulose fibers on the coupling reaction to form insoluble azo dyes and anchor in the fiber. A naphthol can often with different color-diazonium salt coupling from different dyes, with different colors and fastness. Naphthol most varieties from 2-hydroxy-3-carboxylic acid chloride by different after the condensation of aromatic amines which have carbazole, oxygen fluorene, anthracene hydroxyl amine derivatives such as formyl. Naphthol AS for example, naphthol AS-D, naphthol AS-LB, naphthol AS - such as BT.
