| | Acid Green 25 Usage And Synthesis |
| Chemical Properties | dark green powder | | Uses | Acid Green 25 (cas# 4403-90-1) is an organic acid dye. Acid green 25 can undergo colour when co-intercalated with acid yellow 25 into the interlayer of ZnAl layered double hydroxides.Dyes and metabolites. | | Uses | For nylon sutures: Fed. Regist. 42, 52395 (1977). Permitted for use in drugs and cosmetics, excluding use in eye area: ibid. 47, 49628 (1982). | | 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. | | General Description | Fine black or green powder. | | Air & Water Reactions | Slightly soluble in water. | | Reactivity Profile | 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. | | Flammability and Explosibility | Non flammable | | Safety Profile | Moderately toxic by ingestion. Askin and severe eye irritant.
When heated to decomposition it emits very toxic fumesof NOx, SOx, and Na2O. | | 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.] | | 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.
