Questions And Answer	Back Directory
[Application] Potassium chromium hexacyanate is used to prepare an amorphous bimetallic cyanide catalyst with high activity and product regioselectivity.

Hazard Information	Back Directory
[reaction suitability] reagent type: catalyst core: chromium
[Synthesis] Preparaed by Reduce potassium chromate with sulfur dioxide, produce chromium hydroxide with ammonia to convert it to chromium(III) acetate, and then get it with potassium cyanide, or get it by the action of chromium trioxide and potassium cyanide.
[Purification Methods] It forms yellow crystals from water. Recrystallise it two or three times from H2O and dry it over H2SO4. Its solubility at 20o is 30.96g/100g H2O, and it is insoluble in EtOH. Aqueous solutions tend to decompose especially in the presence of light or on heating when Cr(OH)3 separates. [Hein & Herzog in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II pp 1373-1374 1965.]
