1. Potassium ferrocyanide trihydrate is used to manufacture pigments, printing and dyeing oxidizers, potassium cyanide, explosives, and chemical reagents. It is also used for heat treatment of steel, stone printing, carving, etc
2. Potassium ferrocyanide trihydrate is used as an analytical reagent, chromatographic reagent, and developer
3. Potassium ferrocyanide trihydrate is used in the manufacture of pigments, printing and dyeing oxidation aids, paints, inks, potassium erythrite, explosives, and chemical reagents. It is also used in industries such as steel heat treatment, lithography, carving, and pharmaceuticals. Its food additive grade products are mainly used as anti caking agents for table salt.
4. High speed rail reagent (forming Prussian blue). Testing reagents for iron, copper, zinc, palladium, silver, osmium, and protein, as well as urine analysis. Drip analysis of palladium, osmium, and uranium
Packed in 25 kg per drum or based on customers' requirements.
1. Keep it sealed and away from light at room temperature, ventilated and dry
2. Do not store or mix with acids, bases, iron salts, and edible items.
Stability
1. Stable under normal temperature and pressure
2. Avoid materials: oxidizing acids. Soluble in water, insoluble in ethanol, ether, methyl acetate, and liquid ammonia. Heat to 70 ℃ to lose crystal water. When strongly burned, it decomposes and releases nitrogen gas, producing potassium cyanide and iron carbide. Its aqueous solution decomposes into iron hydroxide when exposed to light. When encountering halogen peroxides, it forms potassium hematite. When encountering nitric acid, it first forms potassium hematite, and then forms potassium nitrite containing ferrocyanide K2 [Fe (CN) 5 (NO)]
3. This product is non-toxic, but its raw material cyanide and cyanide produced by thermal decomposition of the product are highly toxic. Treatment and protective measures for cyanide generated during production or decomposition
