Potassic Cyanide~ is an easily fusible and somewhat volatile salt, which, when fused, readily removes oxygen and sulphur from metallic compounds, and forms potassic cyanate or sulphocyanate as the case may be.
Another process consisted in dissolving the cyanate in nitric acid, and precipitating the silver by muriatic acid, the result was 77.
By distilling a dry mixture of cyanate of potassa and sulphovinate of potassa in nearly equivalent proportions.
A current of sulphuretted hydrogen gas is passed through water in which cyanate of silver is diffused, the process being suspended before all the cyanate of silver is decomposed.
Potassium cyanate may be prepared by heating potassium cyanide with an oxidizing agent, or by heating potassium ferrocyanide with manganese dioxide, potassium carbonate or potassium dichromate (J.
Ammonium cyanate possesses considerable theoretical importance since the first synthetical production of an organic from inorganic compounds was accomplished by warming its aqueous solution for some time, urea being formed (F.
Substituted ammonias were also made to combine with cyanic acid, and it was found that the substituted ammonium cyanates produced pass much more readily into the corresponding ureas than ammonium cyanate itself.
The salts of cyanic acid are known as the cyanates, the two most important being potassium cyanate (KOCN) and ammonium cyanate (NH4OCN).
At a little higher temperature it becomes decomposed into ammonia, carbonate, cyanate of ammonium, and cyanuric acid; this latter being left in the retort.
The cyanates of silver, lead, and many other metals may be made by adding a solution of cyanate of potassium to another of a neutral salt of the base.
By acting on the poisoned bread with distilled water and testing the water with ferro-cyanate (prussiate) of potash, the reddish brown precipitate or tint characteristic of copper will appear even with small quantities.
Take an ounce of precipitated Silver to half an ounce of Cyanate of Potash and quarter of an ounce of Hyper Sulphate of Soda.
Then dissolve in the water two ounces of Cyanate of Potash.
In 1827, however, Wohler succeeded in transforming the inorganic ammonium cyanate into the organic urea, and the barrier was broken down.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "cyanate" in a variety of sentences. We hope that you will now be able to make sentences using this word.
