Acid Blue 158 Usage And Synthesis
Uses
C.I. Acid blue 158 is a multifunctional dye. Dyes are important tools in biological experiments. They can help researchers observe and analyze cell structures, track biomolecules, evaluate cell functions, distinguish cell types, detect biomolecules, study tissue pathology and monitor microorganisms. Their applications range from basic scientific research to clinical A wide range of diagnostics. Dyes are also widely used in traditional fields such as textile dyeing, as well as in emerging fields such as functional textile processing, food pigments and dye-sensitized solar cells.
Preparation
4-Amino-3-hydroxynaphthalene-1-sulfonic acid diazo, and 8hydroxynaphthalene-1-sulfonic acid?coupling, and then with excessive sulfuric acid aqueous acid chromium solution common heating, in 115 ℃ : keep 7 hours, make dye create chromium complex.
Contact allergens
This azo dye has the Color Index nr. 14880. It is found in suture materials.
Properties and Applications
green light blue. Dark blue powder. Soluble in water solution for blue. Soluble in alcohol. The strong sulfuric acid for blackish green color, diluted into blue, in the thick of sodium hydroxide solution for purple. Copper ions in dyeing is dark.??Discharge and exhaust dyeing good. For wool dyeing, can also be used for silk, nylon and wool / nylon blended fabric dyeing, but also with cationic dyes in one bath dyeing wool / acrylic blends. Also for wool fabric direct printing and discharge printing. Particularly suitable for woolen fabrics and carpets dyeing, can also be used for leather coloring.
