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.
