Acid Green 25 is incompatible with strong oxidizing agents. . | [Fire Hazard]
Flash point data for Acid Green 25 are not available. Acid Green 25 is probably combustible. | [Preparation]
(a) ?anthracene-1,4,9,10-tetraol?or 1,4-Dihydroxyanthracene-9,10-dione and anthracene-1,4,9,10-tetraol?mixture?with 2 moles of p-Methylaniline in the presence of boric acid condensation; (b) 1,4-Dichloroanthracene-9,10-dione and 2 Moore’s p-Methylaniline?condensation, its product (C.I. Solvent Green 3, C.I. 61565) products, and translate into sodium salt. | [Flammability and Explosibility]
Nonflammable | [Safety Profile]
Moderately toxic by ingestion. Askin and severe eye irritant.
When heated to decomposition it emits very toxic fumesof NOx, SOx, and Na2O. | [Properties and Applications]
blue light green. Green powder. Soluble in water, no solution at room temperature gather the tendency. Soluble in o-chlorophenol, slightly soluble in acetone, ethanol, Pyridine, insoluble in chloroform, toluene. The strong sulfuric acid dyes shows blackish green color, diluted Tracy turn blue; In nitric acid are brown. The little blue water solution, and a blue hydrochloric acid; Add sodium hydroxide is blue light green. Used for wool, polyamide, silk and their blended fabric dyeing and printing. Can also be used in leather, paper, cosmetics, soap, wood, electrical-controlled aluminum and biological color.

| [Purification Methods]
Purify it by salting out three times from an aqueous solution with sodium acetate, followed by repeated extraction with EtOH [McGrew & Schneider J Am Chem Soc 72 2547 1950]. It is a green powder that is slightly soluble in Me2CO, EtOH and pyridine. It is soluble in conc H2SO4 to give a blue solution that becomes turquoise on dilution. [Allen et al. J Org Chem 7 63 1942, Beilstein 14 H 725.] |
