Magnesium Sulphate For Prevention Of Eclampsia

MAGNESIUM SULPHATE

Magnesium sulphate including magnesium sulphate heptahydrate, also known as sulphur bitter, bitter salt, laxative salt, laxative salt, chemical formula for MgSO4-7H2O), is white or colourless needle or oblique columnar crystals, odorless, cool and slightly bitter. Decomposed by heat, it gradually removes the water of crystallisation to anhydrous magnesium sulphate. It is mainly used in the manufacture of fertiliser, tanning, printing and dyeing, catalyst, papermaking, plastics, porcelain, pigment, matches, explosives and fireproof materials, and can be used in printing and dyeing of thin cotton cloth and silk, as the weighting agent of cotton silk and as the filler of cottonwood products, and is used as a laxative salt in medicine.

Fire Fighting Measures
Hazardous characteristics: Not combustible. Decomposes by high heat and releases toxic gases.
Harmful combustion products: sulphur oxide, magnesium oxide.
Fire-fighting methods: Fire-fighters must wear full body fireproof and anti-gas suits and extinguish the fire upwind. When extinguishing the fire, move the container as far as possible from the fire to an open place. Then select the appropriate extinguishing agent to extinguish the fire according to the cause of the fire. 

Preparation Methods
The production process involves the use of various raw materials, including magnesium oxide, magnesium hydroxide, magnesium carbonate, rhodochrosite, and sulfuric acid. These materials are decomposed or neutralised to produce magnesium chloride. Additionally, potassium chloride is produced as a byproduct. Magnesium chloride is then mixed with the magnesium mother liquor in a specific ratio, cooled, and subjected to crystallisation and separation of the crude that. This is followed by heating filtration, the removal of impurities, cooling, and crystallisation of the industrial it. Another method of production is through the heating and concentration of bitter brine, crystallisation and separation or carbonation of magnesium oxide and gypsum water suspension.
