What is Magnesium Chloride Usp?

Magnesium Chloride Usp chemical formula MgCl2. One of the most usual is magnesium chloride hexahydrate, likewise referred to as bischofite, its chemical formula is MgCl2 · 6H2O, and the formula weight is 203.30. The crystals are colorless and also deliquescent monoclinic crystals with a bitter as well as salted preference. The density is 1.569 g/cm3, the melting point is 118 ℃ (decomposition), as well as it is easily soluble in water as well as ethanol. Above 170 ° C, fundamental magnesium chloride and hydrogen chloride are created. At 600 ℃, it disintegrates into magnesium oxide as well as hydrogen chloride.
Anhydrous magnesium chloride is a white lustrous hexagonal crystal, which is easily deliquescence. Odorless. Bitter preference. The loved one molecular mass is 95.22. Thickness 2.32 g/cm3, melting point 714 ℃, boiling point 1412 ℃, a little soluble in acetone, soluble in water, ethanol, methanol and also pyridine. It deliquesces and also smokes in damp air, sublimates when it is white-hot in a stream of hydrogen gas, and is quickly dissolved in water and also sends out warmth violently.

Magnesium Chloride Usp Uses

Preparation Method of Magnesium Chloride Usp

1. Using magnesium metal or Magnesium Chloride Usp as raw material, in the presence of carbon (or carbon monoxide), pass dry chlorine gas to obtain anhydrous magnesium chloride.
2. Mix magnesium chloride hexahydrate and ammonium chloride, add a small amount of water, heat slightly to dissolve it, heat and concentrate under stirring, and precipitate white crystals. After cooling, pulverize the white crystals to obtain ammonium chloride and magnesium chloride. Monohydrate (MgCl2·NH4Cl·H2O). Then heat under reduced pressure, dehydrate at 200 ° C, and then heat up to 300 to 400 ° C, ammonium chloride sublimates, and decomposes during sublimation. After all ammonium chloride sublimates, the residue is quickly taken out in a dry atmosphere, and Sealed to obtain anhydrous magnesium chloride. MgCl2·NH4Cl·H2O→MgCl2·NH4Cl+H2OMgCl2·NH4Cl→MgCl2+NH3+HCl
3. After directly extracting magnesium hydroxide from seawater, magnesium hydroxide is chlorinated to obtain Magnesium Chloride Usp hexahydrate.
4. Decompose magnesium carbonate with hydrochloric acid to obtain anhydrous magnesium chloride.
5. Take the brine after the salt mining as the raw material, concentrate it into a carnallite solution (KCl·MgCl2·6H2O), remove the potassium chloride, then concentrate, filter, cool, crystallize, pass chlorine gas, and repeat the above operation until no potassium Magnesium chloride hexahydrate can be obtained from impurities such as ions, sodium ions, bromine and sulfur dioxide. 6. Treat magnesium oxide with hydrochloric acid to obtain Magnesium Chloride Usp hexahydrate.

The Role of Industrial Magnesium Chloride Usp in Magnesite Products

In magnesite cement products, the role of magnesium chloride mainly has the following three aspects:
1: It can promote the hydration progress of magnesium oxide: due to the hydrolysis of Magnesium Chloride Usp and its neutralization with the hydration product, it promotes the dissolution and hydration of Magnesium Chloride Usp, and finally forms 518 or 518 with magnesium oxide hydrate Mg(OH)2. 318 Crystallization.

2: Increase the content of dispersants in the Mg(OH)2 colloidal solution: The magnesium chloride hexahydrate here acts as a solvent, which accelerates the coagulation and hardening of the system. 3: It can adsorb Mg(OH)2 colloidal particles The moisture between them increases the strength of the product. Magnesium Chloride Usp hexahydrate plays the role of adsorbing the moisture around Mg(OH)2 in this reaction process, so that the 518 phase can be formed as much as possible after the magnesium cement is hardened.
