Potassium ferrocyanide trihyrate Chemical Properties,Uses,Production

Chemical Properties

pale yellow solid

Uses

Applied in formation of a xerogel via a cyanogel the gel has potential use in solid-state gas sensors.1

Uses

Moderately strong oxidizer when coupled with ferricyanide.

Purification Methods

The anhydrous salt is prepared by drying at 110o over P2O5 in a vacuum desiccator. To obtain the trihydrate, it is necessary to equilibrate the salt in a desiccator over a saturated aqueous solution of sucrose and NaCl. It can also be precipitated from a saturated solution at 0o by adding an equal volume of cold 95% EtOH, setting aside for several hours, then centrifuge and wash with cold 95% EtOH. It is finally sucked air dry with water-pump vacuum. The anhydrous salt is obtained by drying the hydrate in a platinum boat at 90o in a slow stream of N2 [Loftfield & Swift J Am Chem Soc 60 3083 1938].
