sodium 4-hydroxy-3-[(2-methoxy-5-nitrophenyl)azo]-6-(phenylamino)naphthalene-2-sulphonate Chemical Properties,Usage,Production

Preparation

2-Methoxy-5-nitrobenzenamine diazo, and ?4-Hydroxy-6-(phenylamino)naphthalene-2-sulfonic acid??in alkaline conditions coupled.

Properties and Applications

brown. Black brown powder. Slightly soluble in water (for blue-ray red), soluble in ethanol (a red light brown), insoluble in other organic solvents. Meet strong sulfuric acid as red light purple, it will be diluted for olive brown; Meet strong sulfuric acid as brown, and soon become yellow light brown. Its water solution with hydrochloric acid produce dark brown precipitation; Add sodium hydroxide produce deep red precipitate. Used for wool fabric, polyamide fiber and silk dyeing and printing.
