Usage

Preparation

7-Aminonaphthalene-1,3-disulfonic acid diazo, and a coupling m-Toluidine?condensation, and then will the nitro reductive into amino, its product to diazo, and 7-(4-Aminobenzamido)-4-hydroxynaphthalene-2-sulfonic acid coupling.

Properties and Applications

red light orange. Soluble in water for orange brown, slightly soluble in ethanol is palm light orange. The strong sulfuric acid for blue-ray in red, for orange brown after diluted. The dye solution to join strong hydrochloric acid have dark brown precipitation; Add thick nitrogen oxidation sodium solution have orange brown precipitation. Used for cellulose fiber dyeing, Exhaust dyeing and levelness are good. Standard Acid Resistance Alkali Resistance Light Fastness Soaping Water Fading Stain Fading Stain AATCC 4-5 3 4 3-4 5
