Abstract
Improvements introduced in the object of the main patent No. 421,512, applied for on December 15, 1973, for: "Procedure for the preparation of Prussian blue", by reaction of calcium or sodium ferrocyanide with a divalent iron salt at pH values less than 7, transformation of the iron acid salt formed from ferrocyanhydric acid into Berlin white, with organic or inorganic salts of potassium at pH values of <1 to 6, and oxidation of the Berlin white to blue of Berlin, characterized in that the potassium or sodium ferrocyanide, the divalent iron salt and the potassium salt are simultaneously present in the reaction vessel and are first reacted at temperatures of approximately 20ºC to approximately 60ºC with the formation of a Berlin white Eventually, the reaction may be carried out more quickly by raising the temperature to boiling temperature.
