10034-96-5 Usage
Chemical Properties
Pale pink crystalline powder, slightly hygroscopic
Uses
Different sources of media describe the Uses of 10034-96-5 differently. You can refer to the following data:
1. Manganese sulfate monohydrate is used to produce manganese by an electrolytic process. The compound is used for dyeing textiles; for producing red glazes on porcelain; in varnish driers; in fertilizers; and in animal feeds to provide manganese as an essential trace element.
2. Manganese Sulfate is a source of manganese that functions as a nutrient and dietary supplement. It exists as a powder which is readily soluble in water.
3. Manganese(II) sulfate monohydrate is used as a colorant in dyes, fertilizers, animal feeds and red glazes on porcelain. Further, it is used in paints, ceramics, nutrient and dietary supplement. It is involved in the preparation of manganese dioxide. In addition, it serves as a precursor to manganese metal and other manganese compounds.
Preparation
Manganese(II) sulfate is prepared by prolonged heating of any manganese salt with concentrated sulfuric acid. The compound is produced commercially from pyrolusite (MnO2) or rhodochrosite (MnCO3). Either mineral is dissolved in sulfuric acid and the solution evaporated:
MnO2 + H2SO4 → MnSO4 + H2O + ? O2
Alternatively, manganese dioxide is heated strongly with dehydrated iron(II) sulfate:
2MnO2 + 2FeSO4 → 2MnSO4 + Fe2O3 + ? O2
Manganese(II) sulfate, prepared by methods involving evaporation of manganese salt with sulfuric acid, is the tetrahydrate, MnSO4?4H2O. The tetrahydrate on gentle heating produces monohydrate, MnSO4?H2O.
Also, manganese(II) sulfate is a by-product in the manufacture of hydroquinone. The process involves reaction of aniline with manganese dioxide in sulfuric acid, followed by the removal of quinone by steam distillation under vacuum.
2C6H5NH2 (aniline) + 5H2SO4 + 4MnO2 → 2C6H4O2 + 4MnSO4 + 2C6H4O2 + 4MnSO4(quinone)
The unreacted acid is neutralized by lime, treated with water, and the solution filtered to separate any excess MnO2 and insoluble residues. Evaporation of the filtrate yields a crude product containing about 80% MnSO4 and 15% (NH4)2SO4.
Manganese(II) sulfate also may be produced by the action of sulfur dioxide with manganese dioxide:
MnO2 + SO2 → MnSO4
General Description
Odorless pale red slightly efflorescent crystals or light pink powder. pH (5% solution) 3.7.
Reactivity Profile
Manganese(II) sulfate hydrate is incompatible with aluminum and magnesium.
Fire Hazard
Flash point data for Manganese(II) sulfate hydrate are not available; however, Manganese(II) sulfate hydrate is probably combustible.
Biochem/physiol Actions
Manganese sulfate has various industrial applications such as dyeing, porcelain glazing, and the manufacture of fertilizers and boiling oils. MnSO4 is used as a source of manganese ion in biological research, such as in culturing of Bacillus licheniformis and the induction of chromosomal abnormalities in plants. MnSO4 has been utilized to investigate the enzyme dependent glycosylation of endogenous glycoproteins in human skeletal muscle.
Purification Methods
Crystallise it from water (0.9mL/g) at 54-55o by evaporating about two-thirds of the water. It dehydrates above 400o.
Check Digit Verification of cas no
The CAS Registry Mumber 10034-96-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,3 and 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 10034-96:
(7*1)+(6*0)+(5*0)+(4*3)+(3*4)+(2*9)+(1*6)=55
55 % 10 = 5
So 10034-96-5 is a valid CAS Registry Number.
