Chemical Properties

red powder

Preparation

2-Amino-5-(4-aminophenyl)benzenesulfonic acid double nitriding, respectively with the 4-(3-Methyl-5-oxo-4,5-dihydropyrazol-1-yl)benzenesulfonic acid and phenol coupling, then use 4-Methylbenzene-1-sulfonyl chloride esterification of hydroxyl phenol.

Properties and Applications

orange. Orange powder, soluble in water. In the red for sulfuric acid, precipitation, diluted into old yellow, precipitation disappeared; In nitric acid to orange. The water solution is orange, join hydrochloric acid or sodium hydroxide colour and lustre is dark. Discharge performance is good. Copper ions and chromium in ion colour and lustre is no change, encounter iron ion turn dark colored. This product is mainly used for wool, silk, jin theory and its blended fabric dyeing and printing, the application of good performance Standard Light Fastness Soaping Persperation Fastness Oxygen bleaching Fastness to seawater Fading Stain Fading Stain Fading Stain ISO(wool) 5 4 5 4 4-5 AATCC(Polyamide) 4-5 4 4
