Sodium Cyanide Production

  • Sodium cyanide Wikipedia

    Production and chemical properties. Sodium cyanide is produced by treating hydrogen cyanide with sodium hydroxide: HCN + NaOH → NaCN + H 2 O. Worldwide production was estimated at 500,000 tons in the year 2006. Formerly it was prepared by the Castner process involving the reaction of sodium amide with carbon at elevated temperatures.
