COBALT CYANIDE Chemical Properties,Usage,Production

  • Physical properties The anhydrous form is a deep-blue powder; hygroscopic; density 1.872 g/cm3; melts at 280°C; insoluble in water. The dihydrate is pink to reddish brown powder or needles; insoluble in water and acids; soluble in sodium or potassium cyanide solutions, ammonium hydroxide, and hydrochloric acid.
  • Uses The compound has limited commercial applications. It is used as a catalyst and in the preparation of cyanide complexes.
  • Preparation The trihydrate salt is obtained as a reddish brown precipitate by adding potasium cyanide to a cobalt salt solution:
    CoCl2 + KCN + 3H2O → Co(CN)2?3H2O + 2KCl
    This on dehydration yields anhydrous Co(CN)2. The Co(CN)2?3H2O precipitate formed above redissolves when excess KCN is added, forming a red solution of potassium cobalt(II) cyanide, K4Co(CN)6. Stoichiomtric amount of KCN should, therefore, be used in the preparation of cobalt(II) cyanide.
  • Hazard The compound is highly toxic by ingestion and possibly through other routes of exposure.
