Solvent Yellow 2 Chemical Properties,Usage,Production

  • Chemical Properties yellow to orange crystalline powder
  • Uses For determination of free HCl in gastric juice; spot test identification of peroxidized fats; pH indicator (red 2.9, yellow 4.0).
  • Definition A banned food coloring.
  • Production Methods 4-Dimethylaminoazobenzene was produced in large quantities in the early 1900s but is currently not produced in any significant commercial quantity in the United States.
  • General Description Yellow crystalline leaflets or an orange powder.
  • Air & Water Reactions Dust may form an explosive mixture in air. Insoluble in water.
  • Reactivity Profile Solvent Yellow 2 can detonate, particularly if sensitized by the presence of metal salts or strong acids. May form toxic gases 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. May form flammable gases with alkali metals. May react explosively with strong oxidizing agents, metal salts, peroxides, and sulfides. May react explosively with strong oxidizing agents, metal salts, peroxides, and sulfides.
  • Hazard Carcinogen.
  • Fire Hazard Flash point data for Solvent Yellow 2 are not available. Solvent Yellow 2 is probably combustible.
  • Safety Profile Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by ingestion and intraperitoneal routes. Experimental teratogenic and reproductive effects. Human mutation data reported. When heated to decomposition it emits toxic fumes of NOx
  • Carcinogenicity 4-Dimethylaminoazobenzene is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity fromstudies in experimental animals.
  • Environmental Fate Chemical/Physical. Releases toxic nitrogen oxides when heated to decomposition (Sax and Lewis, 1987).
    At influent concentrations of 1.0, 0.1, 0.01, and 0.001 mg/L, the GAC adsorption capacities were 249, 140, 83, and 48 mg/g, respectively (Dobbs and Cohen, 1980).
  • Purification Methods Crystallise the dye from acetic acid or isooctane, or from 95% EtOH by adding hot water and cooling. Dry it over KOH under vacuum at 50o. [Beilstein 6 IV 448.] CARCINOGEN.
