Description
Thiourea (also called Thiocarbamide or Sulfourea) is the diamide of
thiocarbonic acid that resembles urea but contains sulfur instead
of oxygen. Thiourea is the main raw material of producing thiourea
dioxide, which presents a white sheen slice, pillar or needle form
shining crystallize body. It can dissolves in cold water, ammonium
sulphur prussic acid and alcohol, also easily dissolves in hot
water, but hardly dissolves in aether.
Thiourea is a fine chemicals product with high additive value,
which is widely applied in various industries such as medicine,
agriculture, textile, printing-dyeing, chemical,
metal-mine-selecting, laundering etc.
It mainly uses in pharmaceutical raw material, bleaching agent in
textile dyeing and printing, auxiliary of dyeing and anti-oxidant,
and it can be used as rubber accelerator, floating agent, photo
developing agent, prexide thiourea, cold wave etc. It is also used
in resin compression molding powder electroplatin blue printing and
boiler washing. In macromolecule material industry, it is used as
catalysis agent and stabilizer of resinic producing, and it is also
used in organic synthesization of sensitizing material, and
medicine, medical, spicery materials in fine chemicals, and also
can be applied in the recycling and separating of heavy metals.
