Basic Orange 2 Usage And Synthesis
  • Chemical PropertiesBORDEAUX TO DEEP PURPLE CRYSTALLINE POWDER
  • UsesOrange dye for cotton and silk.
  • DefinitionA dye made from aniline.
  • General DescriptionRed-brown powder, large black shiny crystals with a green luster or purple powder.
  • Air & Water ReactionsAzo dyes can be explosive when suspended in air at specific concentrations.Slightly soluble in water.
  • Reactivity ProfileBasic Orange 2 is an azo compound. Toxic gases are formed by mixing compounds containing azo groups with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. Basic Orange 2 is incompatible with strong oxidizing agents.
  • HazardQuestionable carcinogen.
  • Fire HazardFlash point data for Basic Orange 2 are not available. Basic Orange 2 is probably combustible.
  • Safety ProfileModerately toxic by ingestion and subcutaneous routes. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. When heated to decomposition it emits very toxic fumes of NO, and HCl. Used as a colorant in textiles, paper, leather, inks, wood, and biological stains
  • Purification MethodsIt is a red-brown powder which is recrystallised from H2O. It gives a yellow solution in conc H2SO4 which turns orange on dilution. Its solubility at 15o is 5.5% (H2O), 4.75% (EtOH), 6.0% (cellosolve), 9.5% (ethylene glycol), 0.005% (xylene) and is insoluble in *C6H6. The hydroiodide has m 184o (from EtOH) and the picrate forms red needles m 196o. [Muramatsu Bull Chem Soc Jpn 31 864 1958, Beilstein 6 IV 561.]
