Sodium ferrocyanide is a sodium salt with a variety of applications. It is primarily used as an anti-caking agent in foods and road salt as well as in the production of colors.
Sodium Ferrocyanide is used primarily as ‘anti-caking agent’ for salt (Nacl)but is used in a wide variety of applications including in the production of Ferricyanides, blue pigments(Iron blues), blue print paper, flotation of ores, pickling of metals, polymerization catalyst, photograph fixing agent, electroplating, as a food additive, fermentation processes of fruit acids (citric acid, tartaric acid etc.), as a gelating agent for removal of heavy metal traces, and in pharmaceutical/chemical industry.
Production of downstream products
With its primary anti-caking function, the most broad use in volume is as an additive to road and food grade salt. When combined with iron, it converts to a deep blue pigment called Prussian blue. It is used as a stabilizer for the coating on welding rods. In the petroleum industry, it is used for removal of mercaptans.
