Author:Amy2022-02-21 16:39:49

Thiourea is an organic sulfur-containing compound with molecular formula CH4N2S. The crystal is white and shiny with bitter taste. The density is 1.41 g/cm and the melting point is 176-178. It is used as a raw material in the manufacture of medicine, dyes,resins,molding powders, etc.Also used as rubber vulcanization accelerator, metal mineral flotation agent. Hydrogen sulfide reacts with lime slurry to produce calcium hydrogen sulfide, which reacts with calcium cyanamide.  


      Material Application:

     

Synthetic methionine and other raw materials.Used as dyes and dyeing auxiliaries,  reasins and press powder raw materials.It can also be used as  rubber vulcanization accelerator, metal mineral flotation agent, catalyst for the preparation of phthalic anhydride and fumaric acid, metal corrosion inhibitor.In photographic materials,can be used as a developer and toner. It can also be used in electroplating industry. Thiourea is also used in diazo photosensitive paper, synthetic resin coatings, anion exchange reasins,budding agents, fungicides and many other aspects. Thiourea is also used as fertilizer, raw material for manufacturing pharmaceuticals, dyes, resins, molding powder, rubber vulcanization accelerator, metal mineral flotation agent,etc.
