Toxicity | LD50 orally in Rabbit: 3250 mg/kg |
colorless or light purple monoclinic crystal, odorless. Deliquescence. Soluble in water, ethanol, acetone, slightly soluble in cold nitric acid. The aqueous solution can be decomposed into ferrous nitrate and oxygen by ultraviolet light. Melting point of 47 deg C; D21168. It decomposes when heated to 100 °c. Mixing with reducing agents, organic matter, combustible materials such as sulfur, phosphorus or metal powder can form an explosive mixture, which can be exploded when heated sharply.
iron filings are added to the nitric acid aqueous solution, heated, after the reaction is completed, the solution is filtered and evaporated until a crystalline film is formed, nitric acid is added, and after stirring, the solution is crystallized at 0 ℃, the crystals were filtered with suction and washed several times with nitric acid to obtain pure ferric nitrate.
used as catalyst, mordant, copper colorant.
rat oral LDso:3250mg/kg. Staff should be protected. If the skin and eyes are touched, they should be immediately rinsed with flowing water. This substance may be harmful to the environment and has an accumulation effect in groundwater. Should be stored separately from flammable, combustible materials, reducing agents, sulfur, phosphorus, etc.

toxicity | has a stimulating effect on the skin, manifested as severe itching of the skin, redness around the hair follicles. Inhalation of dust can cause chronic gastritis, cholecystitis. Production personnel should wear work clothes, protective masks, latex gloves and other labor protection articles. Prevent inhalation of dust, protect the respiratory organs and skin, production equipment should be closed, workshop ventilation should be good, after work to take a bath, protect the skin. |
Use | used as catalyst, mordant, metal surface treatment agent, oxidant, analytical reagent, radioactive material adsorbent. analytical reagent (acetylene absorption), Catalyst, copper colorant |
production method | Iron chipping method nitric acid with a relative density of 1.38 is added to an acid-resistant reactor containing water, the reaction was carried out by heating to 40-50 ° C. And slowly adding fine iron chips for 3H. The solution was heated and the nitrogen oxide gas was extracted. After filtration, the filtrate was evaporated and concentrated until a crystalline film was formed, and the crystals were precipitated by cooling in a cooling crystallizer to 0 ° C. Or lower. After Suction filtration, the crystals were washed with 20% nitric acid. Finished iron nitrate was obtained. The reaction scheme is as follows. Fe 4HNO3 → Fe(NO3)3 NO 2H2OFe 6HNO3 → Fe(NO3)3 3NO2 3H2O mother liquor can be recycled. The nitrogen oxide gas released in the reaction process is commonly absorbed by caustic soda solution in industry, and the neutralization liquid obtained is used for the production of sodium nitrate because of its fast absorption rate. |
