  2. Sodium ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Sodium_ferrocyanide

    Sodium ferrocyanide is produced industrially from hydrogen cyanide, ferrous chloride, and calcium hydroxide, the combination of which affords Ca 2 [Fe(CN) 6]·11H 2 O.A solution of this salt is then treated with sodium salts to precipitate the mixed calcium-sodium salt CaNa 2 [Fe(CN) 6] 2, which in turn is treated with sodium carbonate to give the tetrasodium salt.

  3. Ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Ferrocyanide

    Ferrocyanide is the name of the anion [Fe 6] 4−. Salts of this coordination complex give yellow solutions. It is usually available as the salt potassium ferrocyanide , which has the formula K 4 Fe(CN) 6 .

    Ferrocyanides are used for table salt. [1] The following anticaking agents are listed in order by their number in the Codex Alimentarius by the Food and Agriculture Organization of the UN. 341 tricalcium phosphate; 460(ii) powdered cellulose; 470b magnesium stearate; 500 sodium bicarbonate; 535 sodium ferrocyanide; 536 potassium ferrocyanide

  6. Cyanide - Wikipedia

    en.wikipedia.org/wiki/Cyanide

    The principal process used to manufacture cyanides is the Andrussow process in which gaseous hydrogen cyanide is produced from methane and ammonia in the presence of oxygen and a platinum catalyst. [21] [22] 2 CH 4 + 2 NH 3 + 3 O 2 → 2 HCN + 6 H 2 O. Sodium cyanide, the precursor to most cyanides, is produced by treating hydrogen cyanide with ...

  7. Prussian blue - Wikipedia

    en.wikipedia.org/wiki/Ferric_ferrocyanide

    The iron in this material is all ferrous, hence the absence of deep color associated with the mixed valency. Oxidation of this white solid with hydrogen peroxide or sodium chlorate produces ferricyanide and affords Prussian blue. [23] A "soluble" form, KFe 3+ [Fe 2+ (CN) 6], which is really colloidal, can be made from potassium ferrocyanide and ...

    The safety of sodium ferrocyanide as a food additive was found to be provisionally acceptable by the Committee on Toxicity in 1988. [47] Other anticaking agents sometimes used include tricalcium phosphate , calcium or magnesium carbonates, fatty acid salts ( acid salts ), magnesium oxide , silicon dioxide , calcium silicate , sodium ...
