The production process adopted by our company
Sulfur method: the appropriate amount of water and sulfur powder are stirred into a slurry in a reactor, slowly adding solid sodium cyanide in portions, and reacting at about 110 ° C to form sodium thiocyanate, and then Adding solid ammonium chloride to form ammonium thiocyanate.Then, barium thiocyanate is added to the reaction solution to remove impurities and clarify, and the supernatant liquid is evaporated under reduced pressure to concentrate and precipitate sodium chloride. It is further filtered, cooled, crystallized, separated and dried to obtain ammonium thiocyanate.
What is ammonium thiosulfate?
Ammonium thiocyanate is also known as ammonium thiocyanate, for the synthesis of insecticidesbuprofezinintermediatetert-butylisothiocyanate and insecticideazoximycin, fungicidelevodiazide, herbicide fluoride thiophene Herbicides and the like, and it is also used as an auxiliary raw material for the production of hydrogen peroxide and as a dye, an organic synthesis polymerization catalyst.
What is the difference between ammonium thiosulfate solution and ammonium thiosulfate solid?
Ammonium thiosulfate has different liquid and solid content, the liquid content is 56-60%, and the solid content is about 97%. Ammonium thiosulfate solution can be used directly, and the solid form of ammonium thiosulfate needs to be dissolved.
Ammonium thiosulfate solution Application
1. Ammonium thiosulfate is used as a bactericide and analytical reagent in medicine.
2. Ammonium thiosulfate is used in agriculture to synthesize the intermediate of the insecticide buprofezin, isobutyl isothiocyanate, and the insecticide, zodiazepine, fungicide, leaf azole, herbicide flufenacetate, etc. The intermediate thiosemicarbazide.
3. In addition, it is also used in the manufacture of auxiliary materials and dyes for hydrogen peroxide, organically synthesized polymerization catalystsand the like.
