Description
Verfahren zur Herstellung von Kaliumcyanid oder Kaliumnatriumcyanid aus Kalkstickstoff. Durch Patent 442 966 ist ein Verfahren geschützt, gemäß welchem aus durch Schmelzen von Kalkstickstoff mit Kochsalz enthaltenden Rohschmelzen handelsfähiges. Cyannatriusn gewonnen wird.Process for the production of potassium cyanide or potassium sodium cyanide from calcium cyanamide. Patent 442,966 protects a method according to which from crude melts containing calcium cyanamide with table salt that can be sold. Cyannatriusn is obtained.
Weitere Untersuchungen haben ergeben, daß man das Verfahren des Hauptpatentes auch anwenden kann auf Rohcyanide, welche durch Schmelzen von Kalkstickstoff mit Chlorkalium oder Gemischen von Chlorkalium und Chlornatrium erhalten werden.Further investigations have shown that the process of the main patent can also be used on raw cyanide, which is produced by melting calcium cyanamide with Potassium chloride or mixtures of potassium chloride and sodium chloride can be obtained.
Wie gefunden wurde, erhält man durch Konzentrieren der Lösungen derartiger Schmelzen unter vorausgehender oder gleichzeitiger Ausfällung des Kalks mit Alkalisalzen (Kalium- oder Natriumsalzen oder Gemischen beider), deren Säuren mit Kalk schwer lösliche oder unlösliche Verbindungen zu bilden vermögen, Laugen, welche praktisch nur noch Kaliumcyanid bzw. Kaliumnatriumcyanid enthalten. Die Arbeitsweise entspricht dem im Hauptpatent beschriebenen Verfahren.It has been found that such solutions are obtained by concentrating the solutions Melting with preceding or simultaneous precipitation of the lime with alkali salts (Potassium or sodium salts or mixtures of both), their acids with lime difficult Can form soluble or insoluble compounds, alkalis, which are practical only contain potassium cyanide or potassium sodium cyanide. The way of working corresponds the process described in the main patent.
