• Beschreibung

  Magnesium carbonate is a basic hydrated magnesium carbonate or a normal hydrated magnesium carbonate. It occurs as light, white, friable masses, or as a bulky, white powder. It is odorless, and is stable in air. It is practically insoluble in water, to which, however, it imparts a slightly alkaline reaction. It is insoluble in alcohol, but is dissolved by dilute acids with effervescence.
  Magnesium carbonate is a GRAS substance under the provisions of the Code of Federal Regulations as miscellaneous and/or gen eral purpose food additives. Magnesium carbonate is listed as GRAS substances migrating to food from paper and paperboard products used in food packaging.
  As a general purpose food additive, magnesium carbonate is used as alkali in adjusting the acidity of foods. In addition to the fore going, magnesium carbonate, the most widely used magnesium salt, serves as a drying agent, bleach ingredient, anticaking agent and carrier for other additives. Other uses of magnesium salts include firming agents, lubricants, flavor enhancers, and process ing aids. Pharmaceutically, carbonate is used as antacids.
  Magnesium is an essential nutrient for plants and animals and is a natural constituent of fruits, vegetables, grain, meats and sea foods. It is the fourth most abundant cation in the human body and the second most plentiful intracellularly. The average 60-kg human adult body contains about 24 g magnesium of which about one-half resides in bone. Although plasma levels vary between 1.7 and 3 .0 mg per dl, very little is contained in extracellular fluid. Magnesium is essential for the production and transfer of energy, for protein, fat, and nucleic acid synthesis, for contractility in muscle and excitability in nerve, and for the activity of numerous enzyme systems.

• Verwenden

  Magnesium carbonate basic may be employed for the isolation of carotenoids from grapes during the quantification of carotenoids in grapes by reversed-phase C₃₀ (RP-30) HPLC-DAD-MS (ESI⁺) (High-performance liquid chromatography-diode array detection-mass spectrometry with electrospray ionization) analysis.

• Verwenden

  Magnesium carbonate hydroxide tetrahydrate is used as a mixture with huntite and as filler in polymers. It acts as a flame retardant and fire retardant additive for polymers.

• Allgemeine Beschreibung

  Magnesium carbonate basic (Magnesium hydroxy carbonate) has been synthesized by reacting magnesium hydroxide and carbon dioxide.
