The use and precautions of potassium cyanate

Potassium Cyanate (KCNO) is a white crystalline solid, mainly used for:

Main uses:

● herbicides and insecticides: used in the agricultural field, but their use is limited due to high toxicity.

● Organic synthesis: used as a cyanide source for the preparation of cyanide compounds.

● Metal processing: used as a cleaning agent, etching agent, and deoxidizer for metal surfaces.

● Electroplating field: improving the aesthetic and corrosion resistance of metal surfaces.

Safety precautions:

● Toxicity risk: Potassium cyanate can be absorbed through the respiratory tract, skin, and digestive system, causing neurological damage. When handling, protective equipment should be worn and ventilation should be maintained.

● Emergency measures: If in contact, immediately rinse with clean water and seek medical attention; If ingested by mistake, induce vomiting and seek medical attention.

● Storage requirements: Store in a cool and dark place, away from acidic substances. The molecular formula of

is KCNO, with a density of about 1.525g/cm ³ and a melting point of 350 ℃. It is easily soluble in water and slightly soluble in ethanol.
