Contact SupplierSodium cyanate is isostructural with sodium azide, confirming the linear structure of the cyanate ion. It is made industrially by heating a mixture of sodium carbonate and urea.
Na2CO3+2CO(NH2)2=2NaCNO+CO2↑+2NH3↑+H2O↑
A similar reaction is used to make potassium cyanate. Cyanates are produced when cyanides are oxidized. Use of this fact is made in cyanide decontamination processes where oxidants such as permanganate and hydrogen peroxide are used to convert toxic cyanide to safer cyanate.
