The production process adopted by our company

Sulfur method: the appropriate amount of water and sulfur powder is stirred into a slurry in a reactor, 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, and the like, and it is also used as an auxiliary raw material 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 ibuprofen, isobutyl isothiocyanate, and the insecticide, fungicide, herbicide fluoroacetate, etc. The intermediate thiosemicarbazide.

3. In addition, it is also used in the manufacture of auxiliary materials and dyes for organically synthesized polymerization catalysts and the like.

4. In the photographic industry, it is used as a photographic fixer, which is more soluble in silver halide than sodium salt and has the advantages of short washing time and easy silver recovery.

5. This product is also used as the main component of the silver plating bath in the industry. It is used as a complexing agent in non-cyanide plating, and the thiosulfate is combined with the silver ion to form a complexion of thiosulfate sulfate. The cathode polarization is enhanced to make the silver plating layer crystallized and the covering ability is good. The general dosage is 200-250 g/L. Also used in the synthesis of organic boron compounds, plasticizers, welding flux; metal surface detergent; and aluminum-magnesium alloy casting protection agents.
