Thiourea
Oct 25, 2018

White and shiny crystals. Suffering. The density is 1.41. The temperature of 176 ~ 178 ° C. Decomposes when hotter. Soluble in water, soluble in ethanol when heated, very slightly soluble in ether. Partially isomerization upon melting forms ammonium thiocyanate. It is used as a raw material for the manufacture of drugs, dyes, resins, compression-molding powders, etc., and is also used as a vulcanization accelerator for rubber, a flotation agent for metal minerals, and the like. It is formed by the action of hydrogen sulfide and lime slurry to form calcium sulphate and then reacted with calcium cyanamide. It can also be obtained by melting ammonium thiocyanate or by reacting cyanamide with hydrogen sulfide.

Application:

It is used as a raw material for the synthesis of drugs such as sulfathiazole, methionine and fat pig tablets. Used as a raw material for dyes and dyeing auxiliaries, resins and compression molding powders. It can also be used as a vulcanization accelerator for rubber, a flotation agent for metal minerals, a catalyst for phthalic anhydride and fumaric acid, and as a metal anticorrosive. In terms of photographic materials, it can be used as a developer and a toner. It can also be used in the electroplating industry. Thiourea is also used in many aspects such as diazo photosensitive paper, synthetic resin coating, anion exchange resin, germination accelerator, and bactericide. Thiourea is also used as a fertilizer. [4]

A raw material for producing a drug, a dye, a resin, a compression molding powder, a vulcanization accelerator for rubber, a flotation agent for metal minerals, and the like.
