Product Information :

  • Blue Bird Thiourea dioxide (TDO) is the replacement product for Sodium Hydrosulphite/Sodium Borohydride for the reductive leaching of Clay.
  • TDO Molecular Formula: CH4N2O2S. (CAS Number: 1758-73-2) is also called
    formamidine-sulfinic acid.
  • TDO, when dissolved in 20oC solution, has almost 1040 reducing electric potential, where as Sodium hydrosulfite has 800 and Sodium Borohydride has 480 reducing electric potential.
  • TDO is a strong reductant which re-arranges under alkaline conditions to form formamidine sulphinic acid. This product is also a component of decolorisation agents.
  • TDO has been very effective on a wide variety of applications including leather processing, textile processing, kaolin leaching, paper, pulp and board industry, as bleaching and reducing agents. The application of TDO is crucial to achieve optimal
    brightness gain in the deinking process.
  • TDO saves up to 75% of storage space as the requirement of TDO is only 1/3rd to 1/4th (by volume) of Sodium Hydrosulphite/Sodium Borohydride.
  • TDO 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. This reaction is promoted by the application of heat or in the presence
    of an alkali, and a strong reducing action is thereby exhibited. But, this reaction is slow, and particularly in an acidic to weakly alkaline region.
  • TDO is useful as a reducing agent; it reduces vat dyes, ketones to alcools and hydrocarbons and conjugated unsaturated acids to the corresponding saturated acids. It is an excellent antioxidant in the stabilization of percholorethylene.
