Beschreibung

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Potassium cyanate is an inorganic compound with the formula KOCN. It is the conjugate base of cyanic acid, HOCN. This reagent is used to prepare herbicide. Worldwide production of the potassium and sodium salts was 20 Mkg in 2006. The product is used as a basic raw material for various organic syntheses, for example, urea derivatives, semicarbazides, carbamates and isocyanates. It is also used for the heat treatment of metals. KOCN is prepared by urea with potassium carbonate at 400 °C: 2 OC(NH2)2 + K2CO3 2 KOCN + (NH4)2CO3. The reaction produces a liquid. Intermediates and impurities include biuret, cyanuric acid, and potassium allophanate (KO2CNHC(O)NH2), as well as unreacted starting urea, but these species are unstable at 400 °C.
