Sodium ferrocyanide is the sodium salt of the coordination compound of formula [Fe (CN)6]4−. In its hydrous form, Na4Fe (CN)6·H2O (sodium ferrocyanide decahydrate), it is sometimes known as yellow prussiate of soda.

2009年3月30日 · Sodium ferrocyanide is a coordination compound of sodium, iron, and cyanide. It is added to road and food grade salt as an anticaking agent, and is also used in photography and in the pigment Prussian blue.

Sodium ferrocyanide is a common anti-caking agent. Specialized applications involves their use as precipitating agents for production of citric acid and wine. [2] Ferrocyanide and its oxidized product ferricyanide cannot freely pass through the plasma membrane.

2018年7月25日 · The Panel on Food Additives and Nutrient Sources added to Food (ANS) provided a scientific opinion re‐evaluating the safety of sodium ferrocyanide (E 535), potassium ferrocyanide (E 536), and evaluating the safety of calcium ferrocyanide (E 538) as food additives.

2017年2月15日 · By adding ferrocyanide, the solubility of salt in water decreases so the salt is less likely to dissolve in the moisture coating the crystals. All to say that ferrocyanide reduces the amount of recrystallization.

SODIUM FERROCYANIDE is a coordination compound of iron. The cyanide ligands are tightly bound to the iron, so it is not as toxic as simple inorganic cyanide salts. However, this compound can release hydrogen cyanide gas upon reaction with acids.

Sodium ferrocyanide, also known as tetrasodium hexacyanoferrate or sodium hexacyanoferrate (II), is a coordination compound of formula Na 4 Fe (CN) 6 which forms semi-transparent yellow crystals at room temperature, and which decomposes at its boiling point.

2015年4月16日 · Yellow Prussiate of Soda (YPS, Na 4 [Fe (CN) 6]·10H 2 O) is an approved anticaking agent in table salt. Given that it is a cyanide salt, its use as a food additive is surprising.

Sodium ferrocyanide and potassium ferrocyanide are authorised as feed additives, 3 both with a maximum content of 80 mg/kg sodium chloride (NaCl) (calculated as ferrocyanide anion).
