Introduction: 
Sodium Cyanate is a white or grey white crystalline powder, easily soluble in water(110 g/L (20 ºC)), slightly soluble in chloroform and organic solvents such as benzene, ethanol, ether. Stable under drying condition, while as hydrolysis in hot water, will generate ammonium carbonate, sodium carbonate and urea. When heating up to over 500°C, it also will decompose. Under the catalysis by Ni and Fe, in vacuo, it will decompose into sodium carbonate, sodium cyanide, CO2 and H2O. In case of acids, carbimide/isocyanate produced.Avoid incompatible materials, dust generation, excess heat, strong oxidants.
 
Application: 
Sodium Cyanate is mainly used in agrochemical (an intermediate in the manufacture of insecticides, herbicides), chemical (a raw material for organic synthesis), metallurgical (heat treatment salts for metal), pharmaceutical (raw material), printing and textile (dyestuffs), and photography (initiators) industries.
 
Package and Storage:
Packed in plastic bags with fiber outside, N.W.: 25kg
Stored and transported as non-toxic and non-dangerous goods. Beware of dampness.
 
Compounding Method:
1. Grinding, mixing and heating sodium cyanide and lead monoxide, and then crystallizing in water or dilute ethanol solution, to get the sodium cyanate. 
 
2. Sodium 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.
