- 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.
