káliumcianát

Káliumcianát, also known as potassium cyanate, is an inorganic compound with the chemical formula KOCN. It is a white crystalline solid that is soluble in water and slightly soluble in alcohol. Káliumcianát is a salt formed from the cation potassium (K+) and the cyanate anion (OCN-). The cyanate ion is a linear triatomic ion.

This compound can be produced by heating potassium ferrocyanide with potassium carbonate or by oxidizing potassium cyanide. Káliumcianát has several applications, though it is less common than sodium cyanate. It is used in organic synthesis as a reagent, particularly in the preparation of heterocyclic compounds and isocyanates. It can also be used in some analytical chemistry procedures.

Historically, cyanates have been studied for their potential medicinal properties, though káliumcianát itself is not widely used in pharmaceuticals. It is important to handle káliumcianát with care as it can be toxic if ingested or inhaled, and it can decompose upon heating to release toxic fumes. The compound is generally stored in a cool, dry place away from acids, as contact with acids can liberate toxic hydrogen cyanide gas.
