| Hazard Information | Back Directory | [Chemical Properties]
Bluish-black powder. Soluble in water, the aqueous solution exhibits a reddish-blue to black color. Addition of concentrated hydrochloric acid produces a greenish-blue color. Addition of concentrated sodium hydroxide solution produces a jujube-red color. Dissolved in ethanol, it exhibits a navy blue color. Soluble in ethylene glycol ether, slightly soluble in acetone, and insoluble in other organic solvents. In concentrated sulfuric acid, it exhibits a grayish-blue to black color, which becomes a dark green-blue color upon dilution. In concentrated nitric acid, it exhibits a reddish-brown color that then turns yellow. When dyed in the presence of copper ions, the color becomes darker green, and in the presence of iron ions, the color also becomes darker green. | [Uses]
Acid Black 24 (CAS# 3071-73-6) is a textile, water-soluble dye and organic pollutant. | [Preparation]
5-Aminonaphthalene-1-sulfonic acid diazo, and Naphthalen-1-amine coupling, again diazo, and 8-(Phenylamino)naphthalen-1-ol ? coupling. | [Flammability and Explosibility]
Nonflammable | [Properties and Applications]
blue and black. Blue-black powder. Soluble in water is red light blue or black, soluble in ethanol for navy, slightly soluble in acetone, insoluble in other organic solvents. In a strong sulfuric acid powder blue, it will be a dark green light blue after diluted; In a red light brown nitric acid to yellow. Its water solution and strong hydrochloric acid is green light blue; Add sodium hydroxide fluid shows purplish red color. Dyeing copper ions in a dark green color, also meet iron ion is dark. Used for the Wool Fabric dyeing, especially suitable for kemp products and Wool Blended Fabric dyeing, also can be used for polyamide, silk and leather dyeing. The Barium salt can be used as organic pigments.
