Basic information

Magnesium chloride is an inorganic substance, chemical formula MgCl2, the substance can form a Hexahydrate, Magnesium Chloride Hexahydrate (MgCl2·6H2O), which contains six crystalline waters. In industry, anhydrous Magnesium Chloride is often called Halogen powder, and for Magnesium Chloride Hexahydrate is often called Halogen Piece, Halogen Granular, Halogen Block, etc. Whether Magnesium Chloride Anhydrous or Magnesium Chloride Hexahydrate, they all have a common property: easy to deliquescent, soluble in water. Therefore, we should pay attention to store in a dry and cool place when storing.

Preparation Methods

1.Magnesium Chloride Hexahydrate:Brine, the by-product of salt production from sea water, is concentrated into carnallite (KCl· MgCl·6H2O) solution, removed potassium chloride after cooling, and then concentrated, filtered, cooled and crystallized. Magnesium oxide or magnesium carbonate is obtained by dissolving and replacing with hydrochloric acid.
2.Magnesium Chloride Anhydrous : can be made from a mixture of ammonium chloride and magnesium chloride hexahydrate, or from ammonium chloride, magnesium chloride hexahydrate double salt dehydration in the hydrogen chloride flow and made.Equal molar MgCl2·6H2O and NH4Cl were dissolved in water and crystallized in the form of double salt in an aqueous solution at a temperature slightly higher than 50℃, keeping the original temperature separate from the mother solution.Recrystallize again.

Content analysis

Accurately according to the sample is about 0.5 g, 2 g 50 ml of water and ammonium chloride, dissolves a 8 oxidizing quinoline test solution (TS - l65) 20 ml, join concentrated ammonia solution under stirring (TS - 14) 8 ml, blend in 60 ~ 70 ℃ heating under 10 min, and then let stand for more than 4 h, the precipitation with sand core glass funnel (G3) filter, with warm 1% ammonia liquid washing filter residue, residue, together with the glass funnel dry 3 h under 110 ℃, weighing 8 a quinoline for the oxidation of magnesium (Mg (C9H6NO) 2 · 2 h2o), and then calculate the content of magnesium chloride.
Toxicological data
Acute toxicity: LD50:2800 mg/kg(rat oral).
Ecological data
Slight hazard to water. Do not release materials into the surrounding environment without government permission

Storage method

Storage and transportation temperature: 2-8.Store in a cool, dry and well ventilated warehouse.Keep away from fire and heat.Packing must be completely sealed to prevent moisture absorption.Should be stored separately from oxidizing agent, avoid mixed storage by all means. The storage area shall be provided with suitable materials to hold the leakage.
