Magnesium sulfate

 

Magnesium sulfate is an inorganic substance, metal salt of magnesium and sulfuric acid the formula MgSO4, white powder, forms several crystalline hydrates. In medicine used in the treatment of obesity as a saline laxative, to achieve so called magnesium stress.

Get:

• The interaction of sulphuric acid and magnesium.

• The interaction of sulphuric acid with oxide, hydroxide and carbonate of magnesium.

• Exchange reactions.

• Anhydrous magnesium sulfate get drying of crystalline.

• In industry magnesium sulfate is produced from sea water, minerals kieserite and carnallite.

Sulfate magnesium is a white hygroscopic powder, crystals rhombic crystal structure, the unit cell parameters a = 0,482 nm, b = 0,672 nm, c = 0,833 nm. At a temperature of 1010 °C there is a transition to another orthorhombic phase.

Forms several crystalline hydrates: MgSO4•nH2O, where n = 1, 2, 3, 4, 5, 6, 7, 12. The most studied crystalline — MgSO4•7H2O (epsomite), MgSO4•6H2O and MgSO4•H2O (kiseri).

Soluble in ethanol, glycerol and diethyl ether. Not soluble in acetone.

Included in the main compounds in seawater that is responsible for sound absorption, with this sound energy is converted into heat. The absorption depends on the frequency acoustic oscillations: low-frequency sound is absorbed worse, and high — better (correlation is almost linear in a logarithmic scale of frequency and absorption), which explains the long range transmission of low frequency the sound of the waves.

Applies to:

• Magnesium sulfate is widely used in medicine, usually in the form of a 25% solution, has a multifaceted impact on body. When intravenously quickly reduces the pressure, increasing urine output. If ingestion is poorly absorbed, acts as a laxative also has choleretic effect that is associated with reflexes that occur when the irritation of the nerve endings of the mucous membrane of the duodenum. When parenteral magnesium sulfate has a soothing effect on the Central nervous system. Depending on the doses can be a sedative, hypnotic, or a narcotic effect.

• Magnesium sulfate is used as the additive for road and airfield bases and covers.

• Enters into the composition of magnesia cement.

• In the pulp and paper industry is used as a filler, as well as a component that allows you to save and to improve the physico-mechanical properties of paper when using bleach (especially chlorine) and for the production of fireproof articles of paper.

• Used for cooking flame retardant compositions for impregnating various materials.

• For the production of synthetic detergents means (for example, as a stabilizer of peroxide compounds).

• Widely used in textile industry as a filler material, weighting of silk and cotton, mordant for dyeing fabrics; bleaching component.

• In the laboratory, anhydrous magnesium sulfate is used for drying solvents.

 

Sulfate magnesium technical is Packed in multilayer paper and polypropylene and polyethylene bags weighing 25 kg. in addition, magnesium sulfate can be Packed in plastic bags weighing 0.5 kg or specialized one-time use containers.

Transportation magnesium sulphate is effected by road, rail and water transport. When you use closed transport vehicle. Transportation is carried out in standard packaging or in special containers. For the carriage of magnesium sulfate should protect him from moisture and packaging damage.

Magnesium sulfate should be stored in dry covered warehouses. Storage is in standard factory package stacks. When storage is not you must create stacks above three tiers. When stored should be protected the product from moisture and packing damage.
