Short description

Product name: POTASIUM CYANIDE, Potassium Cyanide Chemical formula: Industrial park Content: 99% Packing specification: 50 kg / carton Origin: USA Apprerance: Powder or tablet form of an eagle Melting temperature: 634 ° C Density: 1.52 g / cm3 Solubility (in water at 25 ° C): 71.6 g / 100 g. Molecule molecule: 65.12 carbon units (dvC). Insoluble when ambient temperature <= 0 ° KCN and sodium cyanide (NaCN) are widely used in organic synthesis for the preparation of nitriles and carboxylic acids, particularly in the von Richter reaction. It also finds use for the synthesis of hydantoins, which can be useful synthetic intermediates, when reacted with a carbonyl compound such as an aldehyde or ketone in the presence of ammonium carbonate.
Description
Potassium cyanide is a compound with the formula KCN. This colorless crystalline salt, similar in appearance to sugar, is highly soluble in water. Most KCN is used in gold miningorganic synthesis, and electroplating. Smaller applications include jewelry for chemical gilding and buffing.

KCN and sodium cyanide (NaCN) are widely used in organic synthesis for the preparation of nitriles and carboxylic acids, particularly in the von Richter reaction. It also finds use for the synthesis of hydantoins, which can be useful synthetic intermediates, when reacted with a carbonyl compound such as an aldehyde or ketone in the presence of ammonium carbonate.

KCN is used as a photographic fixer in the wet plate collodion process. The KCN dissolves silver where it has not been made insoluble by the developer. This reveals and stabilizes the image, making it no longer sensitive to light. Modern wet plate photographers may prefer less toxic fixers, often opting for the less toxic Sodium thiosulphate, but KCN is still used.
