Verfahren zur Umsetzung von Cyanaten in Cyanide.
Es wurde gefunden, dass sich Cyanate durch Einwirkung reduzierender Gase bei erhöhter Temperatur quantitativ in Cyanide umsetzen lassen. Die Cyanate können hiebei in reiner Form oder auch in Gemischen mit ändern Salzen oder Stoffen angewandt werden
Beispiel 1 : Durch geschmolzenes Kaliumcyanat wird bei 750- ('so lange Wasserstoff geleitet. bis das Gas wasserfrei abgeht. Es hinterbleibt eine Schmelze von fast reinem Cyankalium.
Beispiel 2 : l'ber ein Gemenge von Natriul1lcyanat und Magnesia oder (Graphit, welche als indifferente Magerungsmittel dienen, wird bei 700 ('so lange Kohlenoxyd geleitet, bis kein Kohlendioxyd mehr entsteht. Die Schmelze, deren Cyanat nahezu quantitativ in Cyanid umgesetzt ist. kann in an sich bekannter Weise auf Cyannatrium verarbeitet werden.

Process for converting cyanates into cyanides.
It has been found that cyanates can be converted quantitatively into cyanides by the action of reducing gases at elevated temperatures. The cyanates can be used in pure form or in mixtures with other salts or substances
Example 1: Hydrogen is passed through molten potassium cyanate at 750- ('until the gas leaves anhydrous. A melt of almost pure potassium cyanide remains.
Example 2: Carbon oxide is passed over a mixture of sodium cyanate and magnesia or (graphite, which serve as an inert lean agent, until no more carbon dioxide is formed. The melt, the cyanate of which is almost quantitatively converted into cyanide. can be processed on cyan sodium in a manner known per se.
