Open Data Verified Data
Blue monoclinic crystals. Relative density 1. 899(14.8 ℃, heptahydrate), melting point 64 ℃ (heptahydrate). Soluble in water and glycerol, practically insoluble in ethanol. Lose six molecules of crystal water at 90 ℃, lose all crystal water at 300 ℃, in the air gradually weathered, and oxidized to yellow-brown. The interaction of the water-free substance with the water changed back to blue-green. Corrosive. Moisture absorption in dry air.

sulfuric acid iron(2+) salt monohydrate - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | ferrous sulfate monohydrate is a non-toxic, odorless, off-white to off-white, off-white, off-white powder with astringent taste; iron contained in ferrous sulfate monohydrate is a raw material for the synthesis of red blood antibodies in animals. It can be used as a feed-grade mineral feed additive and a blood tonic for livestock and poultry, which can promote the growth and development of livestock and aquatic animals, enhance disease resistance. |
| Application | Iron oxide red and other pigments are produced from ferrous sulfate monohydrate; They are used as herbicides, soil amendments and foliar fertilizers in agriculture, granular products is a very popular fertilizer abroad, can effectively improve the soil, remove moss and lichen; Can also be used as pesticides to control the disease of wheat and fruit trees; Can also be used as a chemical, products for the electronics industry and intermediate raw materials for the biochemical industry. |
| preparation | the method for producing ferrous sulfate monohydrate comprises the following steps: a, ferrous sulfate heptahydrate, a by-product of titanium dioxide production by sulfuric acid method, heating ferrous sulfate heptahydrate to 60~80 ℃, adding the reaction amount of barium oxide, iron and organic flocculant; B, continue to raise the temperature, make the solution boiling, and then stand for 1~4H; c, separating the supernatant, the mixture was heated to boiling, filtered while hot, and the filter cake was dried to obtain ferrous sulfate monohydrate. |
| production method | 1. Sulfuric acid reacts with iron filings, and the slightly acidic ferrous sulfate solution generated by the reaction is clarified to remove impurities, and then cooled to crystallize and dehydrate to obtain ferrous sulfate. Or the ilmenite production of titanium dioxide production by-product of ferrous sulfate by recrystallization refined ferrous sulfate. A monohydrate FeSO4 · H2O can be prepared by heating FeSO4 · 7H2O at 70 ℃ and then at 150~200 ℃ in strong hydrogen flow. |
