Chemical Description

  • Sodium Ferrocyanide, also known as Sodium Hexacyanoferrate(II), is an inorganic compound with the formula Na4Fe(CN)6.
  • It is a crystalline solid, typically appearing as white or colorless crystals.
  • Highly soluble in water, forming a clear solution; insoluble in organic solvents.
  • Stable under normal conditions but may decompose upon heating to release toxic gases, including hydrogen cyanide.
  • Produced industrially through the reaction between hydrogen cyanide, iron(II) salts (such as iron(II) sulfate), and sodium hydroxide.
  • Used as a precursor in the production of other chemicals, such as Prussian Blue pigment and potassium ferrocyanide.
  • Exhibits low acute toxicity, but ingestion or inhalation of large amounts can be harmful.
  • Should be handled with care, following appropriate safety precautions, and stored in a cool, dry place away from incompatible materials.
  • Adherence to regulatory guidelines and safety protocols is essential when handling, transporting, and using Sodium Ferrocyanide to minimize risks to human health and the environment.
  • Sodium Ferrocyanide is commonly used as a stabilizer in certain pharmaceutical formulations.
  • It acts as a complexing agent in various chemical processes, facilitating certain reactions and separations.
  • The compound has been utilized historically in photography as a component in certain photographic processes.
  • In the textile industry, Sodium Ferrocyanide is employed as a dyeing auxiliary, aiding in color development and improvement.
  • It may also find application in certain construction materials as an additive for specific properties, such as anti-caking or coloring.
  • When stored, Sodium Ferrocyanide should be kept away from incompatible materials, such as strong oxidizing agents, to prevent adverse reactions.
  • Transportation of Sodium Ferrocyanide should comply with regulations regarding the handling and transport of hazardous materials.
  • Proper labeling and documentation are necessary for the safe handling and transport of Sodium Ferrocyanide to ensure compliance with regulatory requirements.
  • Sodium Ferrocyanide should only be used by trained personnel following appropriate safety procedures and protocols.
