  Verfahren zur Darstellung von Eisenzyanverbindungen. 



   Die direkte Darstellung von Eisenzyanverbindungen aus Zyanamidsalzen (Na-Ca Salz.) usw. ist bis jetzt noch nicht bekannt. Es wurde nun gefunden, dass man aus dem gesamten Stickstoff der Zyanamidsalze, Eisenzyanverbindungen erhält, wenn man ein Gemenge von Zyanamidsalz und Kohle in ein eisenhaltiges geschmolzenes Alkali oder Erdalkalikarbonat, welchem, zur Erniedrigung des Schmelzpunktes geeignete Salze, beispielsweise   Na Cl etc.,   zugesetzt sind, einträgt. An Stelle von metallischem Eisen können auch Eisenoxyde oder Eisensalze verwendet werden. 



   Ausführungsbeispiel. 



   Darstellung von   Ferrozyanatrium   respektive Ferrozyankalium. 120 kg Soda und   80 kg Chlornatrium   werden geschmolzen, in die Schmelze   13 kg Eisenielle   (bzw.   38 Fe da oder   18-5   5 kg Fez 03   oder 36 kg wasserfreies Fe   SOJ   eingetragen und dann ein Gemisch von 16 kg Kohle und 100 kg Kalkstickstoff (entspricht 16 kg Stickstoff) zugesetzt. Die Schmelze wird ausgelaugt und ergibt

  Process for the preparation of iron cyano compounds.



   The direct preparation of iron cyan compounds from cyanamide salts (Na-Ca salt.) Etc. is not yet known. It has now been found that iron cyanide compounds are obtained from the total nitrogen of the cyanamide salts if a mixture of cyanamide salt and carbon is added to an iron-containing molten alkali or alkaline earth metal carbonate, to which salts suitable for lowering the melting point, for example NaCl etc., are added , enters. Iron oxides or iron salts can also be used instead of metallic iron.



   Embodiment.



   Representation of ferrocyan sodium and ferrocyan potassium. 120 kg of soda and 80 kg of sodium chloride are melted, 13 kg of ferrous (or 38 Fe da or 18-5 kg of Fez 03 or 36 kg of anhydrous Fe SOJ are added to the melt, and then a mixture of 16 kg of coal and 100 kg of calcium cyanamide ( corresponds to 16 kg of nitrogen) The melt is leached out and yields
 EMI1.1
