Description

Potassium thiocyanate, potassium sulfocyanide, potassium sulfocyanate, potassium rhodanate, KCNS, white solid, formed by fusing potassium cyanide and sulfur, and then crystallizing.

Potassium thiocyanate, KSCN,also known as potassium sulfocyanate and potassium rhodanide, is a colorless deliquescent crystalline solid that melts at 173°C (343 OF) and decomposes at 500°C(932 OF). Soluble in water and alcohol,it has no odor and a saline taste.Potassium thiocyanate is used in printing and dyeing textiles, freezing mixtures, manufacturing chemicals, photography and medicine.

ChEBI: A potassium salt which is the monopotassium salt of thiocyanic acid.

A colorless hygroscopic solid. Its solution is used in a test for iron(III) compounds, with which it turns a blood-red color.

Potassium thiocyanate is an inorganic potassium salt. Phase transitions in potassium thiocyanate (KSCN) have been investigated by X-ray diffraction studies. The order-disorder type transition with respect to the orientation of the thiocyanate ions was identified. Itspolarizedinfrared spectrum has been reported. It participates in the ring-opening of aziridines. The reaction was carried out in the presence of sulfated zirconia to afford the corresponding β-aminothiocyanates.

Potassium thiocyanate Use and Manufacturing

It can be used in electroplating industry for stripping agent, it can also be used refrigerant. It can also be used in the dye industry, photographic industry, pesticides and steel analysis.

Analysis of siliver ion; indirect determination of chloride, bromide, and iodide.

manufacture of artificial mustard oil; printing and dyeing textiles; in photography as intensifier; in analytical chemistry. The sodium salt now is replacing it for most of these uses.

Used as a source of thiocyanate.

Potassium Thiocyanate has been used as a catalyst in a one-pot reaction of dialkyl acetylenedicarboxylates with indane-1,3-dione. Potassium Thiocyanate has been used as a selective bacterial inhibitor to create ESS-3 broth to allow co-enrichment of the target pathogens and suppress growth of some non-target pathogens
