Is this chemical reaction correct? Is such a reaction possible?

K4Fe(CN)6• 3H2O + K2CO3 --> 6KCN + CO2 + FeO + 3H2O

According to 1911 Encyclopaedia Britannica - yes & yes:

When (potassium ferrocyanide is) fused with potassium carbonate it yields potassium cyanide
Compare http://en.wikisource.org/wiki/1911_E...a/Prussic_Acid

Please note KCN is highly toxic, so we will not discuss any further details here.

In a water solution nothing happens because the Ferrocyanide anion is too stable. That's why it needs to be done in the dry state and high temperature.
