1,-Naphthalenedisulfonic acid, 4,4'-[carbonylbis[imino(5-methoxy-2-methyl-4,1-phenylene)azo]]bis-, tetrasodium salt Chemical Properties,Usage,Production
Preparation
4-Aminonaphthalene-1,6-disulfonic acid?or 4-Aminonaphthalene-1,7-disulfonic acid?diazo, and 2-Amino-4-methylanisole coupling, and then make the light gasification.
Properties and Applications
orange. Soluble in water for orange, slightly soluble in alcohol. The strong sulfuric acid for blue, green light blue after diluted precipitation. The dye solution to join strong hydrochloric acid have hidden cyan precipitation; Add thick sodium hydroxide solution have orange precipitation. Used for cellulose fiber dyeing and printing, and can be used in the paper color. 80 ℃ with the biggest dyeing affinity, good levelness.
