Synthetic method:

 

1,Take the sodium cyanide and lead oxide by the research and total heat, and then crystallization in   

   water or dilute ethanol solution.

2.Take the sodium and urea reaction on gas lamps.

 

The last remaining melt of sodium cyanate, non impurity is colorless and the impurities is brown. the test must be carried out in a fume hood,because the molten toxic of sodium cyanate will be volatile.

 

Packaging and storage

 

Packaged in woven bags (N.W:25kg)

 

The Sodium cyanate should be stored in a cool and dry of storehouse,it’s stored separately with acids and food additives.
