Potassium thiocyanate, molecular formula is KSCN, it is also known as KSCN, English is Potassium Thiocyanate, it is colorless monoclinic crystal. The relative density is 1.886. Melting point is about 172.3 ℃. It is soluble in water and it can cool because of the absorption of heat, it is also soluble in alcohol (ethanol) and acetone. Crystalline hemihydrate (KSCN.0.5H2O) can be obtained at low temperature, it is steady at-29-6.8℃, and it can turn blue when be broiled at about 430℃, but it then re-becomes colorless when be colded. When be heated to 500℃, it can decompose. The blood red ferric thiocyanate complex ion FeSCN2 + (iron thiocyanate) can generate in case of Fe3 + (ferric), which is the sensitive method to test the Fe3 + ion, the method can eliminate the influence of all other known metal ions. And it can not react with ferrous salts. It is hygroscopic, and it should be sealed. It has low toxicity. But potassium cyanate is highly toxic substances, the country has limited its production.
1.Analysis of siliver ion; indirect determination of chloride, bromide, and iodide.
2.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.
3.Used as a source of thiocyanate.
4.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
