Barium Cyanate, Ba(CNO)₂

Barium Cyanate, Ba(CNO)₂, may be prepared by adding alcohol to a solution of a mixture of potassium cyanate and barium acetate, or, more readily, by heating barium cyanurate until it melts, when it is converted into barium cyanate. The salt crystallises in prisms, and its solution decomposes on boiling with formation of urea and barium carbonate

Ba(CNO)₂ + 3H₂O = BaCO₃ + (NH₂)₂CO.
