Magnesium sulfate

Also known as Epsom salt, sulfur, bitter salt, diarrhea salt; chemical formula MgSO4; melting point 1124 ° C; density 2.66 g / mL
magnesium sulfate, or anhydrous magnesium sulfate, is a magnesium-containing compound, anhydrous magnesium sulfate is a kind Commonly used chemical reagents and desiccant, but magnesium sulfate is often referred to as magnesium sulfate heptahydrate, which is a small white oblique or oblique columnar crystal. It is odorless and bitter. It is clinically used for catharsis, gallbladder, anticonvulsant, tetanus. , high blood pressure and other diseases.
Chemical properties: white or colorless needle-like or oblique columnar crystal, odorless, cool and slightly bitter, molecular weight: 246.47, specific gravity 1.68, soluble in water, slightly soluble in ethanol and glycerin, soluble in 67.5 ° C Crystal water. Decomposed by heat, 70, 80 ° C is the loss of four molecules of crystal water. At the 200 ° C of the month, all the crystal water was lost to an anhydrate. It is easily weathered into powder in air (dry), and gradually removes crystal water into anhydrous magnesium sulfate when heated. This product does not contain any toxic impurities. Magnesium sulfate heptahydrate is easier to weigh than anhydrous magnesium sulfate because it is not easily dissolved, which facilitates quantitative control in the industry.
Uses: Manufacture of fertilizers, tanning, printing and dyeing, catalysts, paper, plastics, porcelain, pigments, matches, explosives and fireproofing materials. It can be used for printing and dyeing thin cotton cloth, silk, as a weighting agent for cotton silk and filler for kapok products: it is used as an elixir salt in medicine.
