PROCESS FOR THE PRODUCTION OF ALKALI FERROCYANIDE

Alkali ferrocyanides are prepared by converting calcium hexacyanoferrate (II) with an iron (II) salt to an iron (II) hexacyanoferrate (II), washing the complex with water until free of calcium ions and then reacting further with sodium, potassium or ammonium cyanide.
