magnesium sulphate monohydrate Chemical Properties,Uses,Production
Chemical Properties
colorless crystal(s); monoclinic, a=0.690nm, b=0.771 nm, c=0.754nm [KIR81]
Uses
Magnesium sulfate monohydrate can be used:
- As a precursor to synthesize magnetic manganese ferrite nanoparticles by alkaline coprecipitation.
- To fabricate manganese octahedral molecular sieve (OMS-2) catalysts for selective aerobic oxidation of aromatic and aliphatic thiols.
- As a catalyst to synthesize benzo-2-pyrones and benzopyrazines.
- As a precursor to synthesize manganese oxide nanoparticles for energy storage applications.
Agricultural Uses
Kieserite is a greyish-white crystalline powder which contains about 16% magnesium and is used as a fertilizer. It is regarded as a concentrated form of epsom salt, having less water of crystallization. The monohydrate MgSO4·H2O(m onoclinic) occurs in nature as kieserite which contains 27% magnesium (as MgO) and 22% sulphur.
Synthesis
The production principle of magnesium sulfate monohydrate is that concentrated sulfuric acid reacts directly with light burnt powder (bituminous earth powder) or crushed magnesite raw ore to obtain fertilizer grade magnesium sulfate monohydrate. The following is a detailed summary: First sulfuric acid and magnesium oxide-containing mineral powder (dolomite, rhodochrosite, serpentine) or its calcined powder according to the proportion of measurement; in the neutralization tank to add water or wash water, mother liquor, in the stirring under the Xu Xu added mineral powder, then add sulfuric acid for neutralization reaction, control slurry pH = 5, the density of 1.370 ~ 1.384g/cm3; will be neutralized to maintain the liquid reaction of 80 degrees for a certain period of time, through the blade filter filtering, the clear liquid into the crystallizer. Clear liquid into the crystallizer; cooling to below 30 degrees, centrifugal separation (can be washed in the centrifuge), the wet material into the dehydration dryer, dehydration and drying at more than 200 degrees to produce magnesium sulfate monohydrate.
