Versorgung Thiourea

I. Description of the ProductThiourea (also called Thiocarbamide or Sulfourea) is the diamide of thiocarbonic acid thatresembles urea but contains sulfur instead of oxygen. Thiourea is the main raw material ofproducing thiourea dioxide, which presents a white sheen slice, pillar or needle formshining crystallize body. It can dissolves in cold water, ammonium sulphur prussic acidand alcohol, also easily dissolves in hot water, but hardly dissolves in aether. II. Applications of the ProductThiourea is a fine chemicals product with high additive value,which is widely applied invarious 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 andprinting, 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 inresin compression molding powder electroplatin blue printing and boiler washing. Inmacromolecule material industry, it is used as catalysis agent and stabilizer of resinicproducing, and it is also used in organic synthesization of sensitizing material, andmedicine, medical, spicery materials in fine chemicals, and also can be applied in therecycling and separating of heavy metals.III.
