Contents on the CD Rom

  • Thiourea occurs as white, lustrous crystals or flaky solids. It is soluble in water, ammonium thiocyanate solution, and ethanol, and almost insoluble in ether.
  • Thiourea dioxide is also called formamidine-sulfinic acid or aminoiminomethanesulfinic acid and is often abbreviated as TDO or TUD.
  • Thiourea dioxide is a powdered stable compound, which dissolves in water and decomposes gradually to produce sulfoxylic acid through formamidine-sulfinic acid to exhibit a reducing action.
  • Thiourea is a lustrous white crystalline compound and its estimated melting point is 170-180 C and soluble in water and in polar organic solvents; insoluble in non-polar solvents.
  • Decolorizing the natural color of pigmented fibers, such as cashmere, camel hair, human hair and contaminated dark fibers in white wool, brings about by the following three sequential processes: mordanting, specific rinsing and alkaline hydrogen peroxide bleaching.
  • Thiourea dioxide (formamidinesulfinic acid or aminoiminomethanesulfinic acid, abbreviated as aimsa) can easily be prepared via the oxidation of thiourea with aqueous solutions of hydrogen peroxide.
  • Thiourea dioxide (TDO) product is used in leather processing industry, paper, pulp and board industry, photographic industry, textile processing industry, bleaching and reducing agents. This product is also a component of decolorisation agents.
  • It has been used as a photographic toning agent, in hair preparations, as a dry cleaning agent, in the synthesis of pharmaceuticals and insecticides, in boiler water treatment, and as a reagent for bismuth and selenite ions.
