As a chemical intermediate, in electroplating, as a pesticide and medicinally as a hematinic. Registered by EPA as a herbicide (cancelled). Blue-green monoclinic crystals d n 1.897 loses H2O to form the tetrahydrate at 56.6", and the monohydrate at 65" soluble in H2O, insoluble in EtOH LDso (mus iv) n 65 mg/kg, (mus orl) = 1520 mg/kg.

L bioreactor. To this was added 0.88 g ascorbic acid, 0.28 g iron sulfate heptahydrate 17.1 g 2-oxoglutarate, and 10 g L-proline as substrate. The reaction was stirred at 30°C and at pH 7.0 for 24 h. It was found that the yields of the reaction were improved through the addition of both 2-OG (8 g/h) and ascorbate (3 g/h) during the reartion. The reaction was monitored by HPLC.

The main impurity of the filtrate is the iron(II) sulfate which can be crystallized as the heptahydrate, FeS04-7H2 O, by cooling the solution to a temperature below 15°C. This process is most often carried out in vacuum crystallizers. The crystals of iron sulfate are separated by centrifugation or filtration (qv). To prevent premature hydrolysis of titanium dioxide, the temperature of the above processes should not exceed 70°C. 

The largest volume of synthetic red iron oxide is produced by the two-step calcination of iron(II) sulfate. In the first step, the iron(II) sulfate heptahydrate is dehydrated to a monohydrate ...

FIGURE E.5 Each sample contains 1 mol of formula units of an ionic compound. From left to right are 58 g of sodium chloride (NaCl), 100 g of calcium carbonate (CaCO,), 278 g of iron(ll) sulfate heptahydrate (FeS04-7H.0), and 78 g of sodium peroxide (Na. O,). 

Iron(II) sulfate in industrial scale is mostly produced in the pickling process as a by-product of the steel industry. It is obtained when the surface of steel is cleaned with dilute sulfuric acid to remove metal impurities. In the laboratory iron(II) sulfate heptahydrate may be prepared by dissolving iron in dilute sulfuric acid in a reducing atmosphere, followed by crystallization ... 

Sulfates. Iron(II) sulfate heptahydrate [7782-63-0], FeS04TH O, forms blue-green monoclinic crystals that are very soluble in water and somewhat soluble in alcohols. It is known by many other names including cupperas, green vitriol, and iron vitriol. The compound is efflorescent in dry air. In moist air, the compound oxidizes to yellow-brown basic iron(III) sulfate. Aqueous solutions tend to oxidize. The rate of oxidation increases with an increase in pH, temperature, and light. The compound loses three waters of hydration to form iron(II) sulfate tetrahydrate [20908-72-0], FeS04 TH O, at... 

About 70% of all iron oxide pigments are produced synthetically. Copperas or ferrous sulfate heptahydrate (FeS04-7H20) is the primary source of iron. It is a byproduct of the sulfate process for the manufacture of titanium dioxide as well as a by-product of pickling operations in the steel industry. Other sources of iron include ferric sulfate, ferrous chloride, ferric chloride, and the iron oxide slurry from the production of aniline by nitrobenzene reduction.
