| Application: | Potassium cyanide may be employed in the following studies: • As a reducing agent in the colorimetric determination of amino acids. • Preparation of ferrocylacetonitrile, via reaction with methiodide of N,N-dimethylaminomethylferro • Synthesis of O-acetylcyanohydrins. • Cyanation of aldimines via asymmetric Strecker-type reactions in the presence of chiral phase-transfer catalysts to form α-amino nitriles. • Metal-catalyzed addition of cyanide to 1,2-epoxides to form β-hydroxy nitriles. |
| General description: | Potassium cyanide is a colorless hygroscopic compound. Its crystals exhibit cubic crystal system. It can be prepared by reacting hydrogen cyanide with potassium hydroxide. It participates in benzoin condensation reaction. |
