Magnesium Chloride Anhydrous

  • Magnesium Chloride Anhydrous is a crystalline solid chemical compound. The crystal structure of MgCl2 is layer-like. It is very hygroscopic and highly soluble in water and alcohol. It can be prepared by heating hydrated magnesium chloride crystals in a current of dry hydrogen chloride or by heating magnesium ammonium chloride. Anhydrous magnesium chloride contains 25.5% elemental magnesium by mass. It is the principal precursor to magnesium metal, which is produced on a large scale. Anhydrous magnesium chloride is supplied in flake and powder forms.

Magnesium Chloride Basic Information

Magnesium chloride is an inorganic chemical compound. It has various hydrated forms (MgCl2.XH2O) and anhydrous form (MgCl2).

Hexahydrate magnesium chloride (MgCl2.6H2O) is easily accessible from the natural brine or salt lake brine. Hexahydrate magnesium chloride CAS No.:7791-18-6, HS code: 282731000.

Anhydrous magnesium chloride (MgCl2) has no crystal water, it contains approximately 25.5% magnesium by mass. Anhydrous magnesium chloride is the primary material for the production of magnesium metal. Anhydrous magnesium chloride CAS No.:7786-30-3, HS code: 282731000.

Typical applications of magnesium chloride:

  1. Magnesium chloride is highly hygroscopic, can be used as a desiccant; 
  2. Dissolving in water, magnesium chloride releases large amount of heat, can used as a ice melter.
  3. When heating ,magnesium chloride releases chlorine to stop fire, can be used as a flame retardant. Magnesium chloride has many other applications.

Magnesium Chloride Anhydrous Vs. Hexahydrate

    Magnesium chloride is a commonly used chemical product in the chemical industry. At present, the products on the market are mainly anhydrous magnesium chloride and magnesium chloride hexahydrate. They have similiar physical properties.
    1. Differences in production process
    ①.Magnesium chloride hexahydrate is the mother liquor after bromine production (bromine mother liquor is an unsaturated aqueous solution of magnesium chloride), and then evaporated and concentrated (normal pressure evaporation and reduced pressure evaporation are usually used), and finally hexahydrate is obtained Magnesium chloride products;
    ②. Magnesium chloride Anhydrous can be made from a mixture of ammonium chloride and magnesium chloride hexahydrate, or a double salt of ammonium chloride and magnesium chloride hexahydrate dehydrated in a hydrogen chloride stream.
    2. Molecular formula difference
    ①. Magnesium chloride hexahydrate has six crystal waters, the molecular formula is MgCl2.6H2O;
    ②. Anhydrous magnesium chloride does not contain crystal water, and its molecular formula is MgCl2.
    3. Appearance difference
    ①. Magnesium chloride hexahydrate is white to brown flakes or colorless crystals, which are often called halogen flakes, halogen grains, halogen blocks, etc. in the industry; magnesium chloride hexahydrate flakes are thicker than anhydrous magnesium chloride flakes.
    ②. Anhydrous magnesium chloride is a white shiny hexagonal crystal, which is often called halogen powder in the industry.
    4. Deliquescent difference
    ①. Magnesium chloride hexahydrate is easy to deliquescence in humid air;
    ②. The deliquescence of anhydrous magnesium chloride is higher than that of magnesium chloride hexahydrate, and the deliquescent speed is relatively slower.
    5. Use difference
    ①. Magnesium chloride hexahydrate can be used in food industry, building materials industry, cement industry, deicing agent, desiccant, animal husbandry and aquaculture, pulping, magnesium fertilizer, sewage treatment, etc.;
    ②. Anhydrous magnesium chloride is mainly used in metallurgy, light industry, coal, construction, chemical and other industries.
