Magnesium is a mineral responsible for many body functions, including muscle and nerve function, regulating blood sugar and blood pressure levels, and making protein, bones, and DNA.1 Magnesium is naturally present in many foods, including whole grains, leafy vegetables, nuts and legumes, fortified foods, and dairy.
E509 (Magnesium Chloride) is one of several types of magnesium supplements.
Others include magnesium aspartate, magnesium citrate, magnesium gluconate, magnesium glycinate, magnesium lactate, magnesium malate, magnesium oxide, and magnesium sulfate.
Uses of E509 (Magnesium Chloride):
Supplement use should be individualized and vetted by a healthcare professional, such as a registered dietician, pharmacist, or doctor.
No supplement is intended to treat, cure, or prevent disease.
People mainly use E509 (Magnesium Chloride) to boost their dietary intake of magnesium.
While it doesn't treat conditions by itself, it can help those with low magnesium levels improve certain bodily functions.
In addition, E509 (Magnesium Chloride) supplements have well-documented uses in type 2 diabetes, high blood pressure, osteoporosis, and migraines.
Other:
In addition to the potential health benefits listed above, some people use magnesium to support:
*Sleep
*Mood
*Energy
E509 (Magnesium Chloride) is the name for the chemical compound with the formula MgCl2 and its various hydrates MgCl2(H2O)x.
Anhydrous MgCl2 contains 25.5% elemental magnesium by mass.
These salts are typical ionic halides, being highly soluble in water.
The hydrated E509 (Magnesium Chloride) can be extracted from brine or sea water.
In North America, E509 (Magnesium Chloride) is produced primarily from Great Salt Lake brine.
E509 (Magnesium Chloride) is extracted in a similar process from the Dead Sea in the Jordan Valley.
E509 (Magnesium Chloride), as the natural mineral bischofite, is also extracted (by solution mining) out of ancient seabeds, for example, the Zechstein seabed in northwest Europe.
Some E509 (Magnesium Chloride) is made from solar evaporation of seawater.
Anhydrous E509 (Magnesium Chloride) is the principal precursor to magnesium metal, which is produced on a large scale.
Hydrated E509 (Magnesium Chloride) is the form most readily available.
Structure, preparation, and general properties:
E509 (Magnesium Chloride) crystallizes in the cadmium chloride motif, which features octahedral Mg centers.
Several hydrates are known with the formula MgCl2(H2O)x, and each loses water at higher temperatures:
x = 12 (−16.4 °C), 8 (−3.4 °C), 6 (116.7 °C), 4 (181 °C), 2 (about 300 °C).
In the hexahydrate, the Mg2+ is also octahedral, but is coordinated to six water ligands.
The thermal dehydration of the hydrates MgCl2(H2O)x (x = 6, 12) does not occur straightforwardly.
Anhydrous E509 (Magnesium Chloride) is produced industrially by heating the chloride salt of hexammine complex [Mg(NH3)6]2+.
As suggested by the existence of some hydrates, anhydrous E509 (Magnesium Chloride) is a Lewis acid, although a weak one.
In the Dow process, E509 (Magnesium Chloride) is regenerated from magnesium hydroxide using hydrochloric acid:
Mg(OH)2(s) + 2 HCl(aq) → MgCl2(aq) + 2 H2O(l)
E509 (Magnesium Chloride) can also be prepared from magnesium carbonate by a similar reaction.
Derivatives with tetrahedral Mg2+ are less common.
Examples include salts of (N(C2H5)4)2MgCl4 and adducts such as MgCl2.
APPLICATIONS
*Precursor to Mg metal
Anhydrous E509 (Magnesium Chloride) is the main precursor to metallic magnesium.
The reduction of Mg2+ into metallic Mg0 is performed by electrolysis in molten salt.
As it is also the case for aluminium, an electrolysis in aqueous solution is not possible as the produced metallic magnesium would immediately react with water, or in other words that the water H+ would be reduced into gaseous H2 before Mg reduction could occur.
So, the direct electrolysis of molten MgCl2 in the absence of water is required because the reduction potential to obtain Mg is lower than the stability domain of water on an Eh–pH diagram.
MgCl2 → Mg + Cl2
The production of metallic magnesium at the cathode (reduction reaction) is accompanied by the oxidation of the chloride anions at the anode with release of gaseous chlorine.
This process is developed at a large industrial scale.
*Dust and erosion control
E509 (Magnesium Chloride) is one of many substances used for dust control, soil stabilization, and wind erosion mitigation.
When E509 (Magnesium Chloride) is applied to roads and bare soil areas, both positive and negative performance issues occur which are related to many application factors.
*Catalyst support
Ziegler-Natta catalysts, used commercially to produce polyolefins, contain E509 (Magnesium Chloride) as a catalyst support.
The introduction of E509 (Magnesium Chloride) supports increases the activity of traditional catalysts and allowed the development of highly stereospecific catalysts for the production of polypropylene
*Ice control
E509 (Magnesium Chloride) is used for low-temperature de-icing of highways, sidewalks, and parking lots.
When highways are treacherous due to icy conditions, E509 (Magnesium Chloride) helps to prevent the ice bond to the pavement, allowing snow plows to clear the roads more efficiently.
E509 (Magnesium Chloride) is used in three ways for pavement ice control:
Anti-icing, when maintenance professionals spread it onto roads before a snow storm to prevent snow from sticking and ice from forming; prewetting, which means a liquid formulation of E509 (Magnesium Chloride) is sprayed directly onto salt as it is being spread onto roadway pavement, wetting the salt so that it sticks to the road; and pretreating, when E509 (Magnesium Chloride) and salt are mixed together before they are loaded onto trucks and spread onto paved roads.
Calcium chloride damages concrete twice as fast as E509 (Magnesium Chloride).
The amount of E509 (Magnesium Chloride) is supposed to be controlled when it is used for de-icing as it may cause pollution to the environment.
*Nutrition and medicine
E509 (Magnesium Chloride) is used in nutraceutical and pharmaceutical preparations.
*Cuisine
E509 (Magnesium Chloride) is an important coagulant used in the preparation of tofu from soy milk.
E509 (Magnesium Chloride) is an inexpensive dietary supplement providing magnesium, hence its interest in view of a general deficit in our current consumption (to be in full health, the human body must in particular benefit from a balance between calcium and magnesium).
E509 (Magnesium Chloride) is also an ingredient in baby formula milk.
*Gardening and horticulture
Because magnesium is a mobile nutrient, E509 (Magnesium Chloride) can be effectively used as a substitute for magnesium sulfate (Epsom salt) to help correct magnesium deficiency in plants via foliar feeding.
The recommended dose of E509 (Magnesium Chloride) is smaller than the recommended dose of magnesium sulfate (20 g/l).
This is due primarily to the chlorine present in E509 (Magnesium Chloride), which can easily reach toxic levels if over-applied or applied too often.
E509 (Magnesium Chloride) has been found that higher concentrations of magnesium in tomato and some pepper plants can make them more susceptible to disease caused by infection of the bacterium Xanthomonas campestris, since magnesium is essential for bacterial growth
Occurrence:
Magnesium values in natural seawater are between 1250 and 1350 mg/l, around 3.7% of the total seawater mineral content.
Dead Sea minerals contain a significantly higher E509 (Magnesium Chloride) ratio, 50.8%.
Carbonates and calcium are essential for all growth of corals, coralline algae, clams, and invertebrates.
Magnesium can be depleted by mangrove plants and the use of excessive limewater or by going beyond natural calcium, alkalinity, and pH values.
The most common mineral form of E509 (Magnesium Chloride) is its hexahydrate, bischofite.
Anhydrous compound occurs very rarely, as chloromagnesite.
E509 (Magnesium Chloride)-hydroxides, korshunovskite and nepskoeite, are also very rare
