Preparation

2-[2-Amino-5-[4-amino-3-(carboxymethoxy)phenyl]-phenoxy]acetic acid double nitriding, and 4-Hydroxy-7-(4-methoxyphenylamino)naphthalene-2-sulfonic acid (2 Moore) coupled.

Properties and Applications

dark blue. Dark grey powder. Soluble in water, slightly soluble in alcohol. The strong sulfuric acid dyes for blue, diluted into purple, have precipitation. The dye water solution is colourful blue, join after strong hydrochloric acid is still bright blue, accompanied by precipitation; Add thick sodium hydroxide solution to deep purple, have precipitation. Copper ions in dyeing color shade basically unchanged, iron ion in the green light and dark. Used for cotton, viscose and their blended fabric, silk, leather and paper dyeing and printing
