Mordant Black 17 Usage And Synthesis

Chemical Properties

dark brown to purple powder

Uses

Mordant Black 17 can be prepared to use as blue acid dye.

Preparation

4-Amino-3-hydroxynaphthalene-1-sulfonic acid diazotization, and Naphthalen-2-ol coupling.

Properties and Applications

dark red light navy blue to black. Dark brown powder. Soluble in water for wine red to purplish red, in the water solubility is 50 g/l (80 ℃), soluble in Cellosolve, slightly soluble in ethanol and Acetone, insoluble in other organic solvent. In concentrated sulfuric acid for blue, dilution after pale red light brown, precipitation, In concentrated nitric acid for yellow; In 10% of sodium hydroxide solution to red. Its aqueous solution to join concentrated hydrochloric acid into olive yellow brown, precipitation, Add people concentrated sodium hydroxide solution into purple black. Dyeing encounter copper ion colour and lustre more red, can’t and iron ion contact. Mainly used for wool fabric and silk and nylon after chrome dyeing, but also can be used for wool and a variety of fiber blended fabric dyeing. Can be in acetic acid chromium pretreatment of wool fabric direct printing, also can be used for leather and biological dyeing. Is tasted can be used for indicator.

Purification Methods

Free it from metallic impurities by three precipitations from aqueous solution by addition of HCl. The precipitated dye is dried at 60o under vacuum and converted into the Na salt with the calculated amount of alkali. It is an indicator in the complexometry of Al, Fe and Zr.
