• Beschreibung

  Magnesium silicate is very important in the earth sciences because it is the material that makes up most of the volume of the Earth. Magnesium silicate can be prepared by calcining the oxide with silica, SiO2, at an elevated temperature.

• Chemische Eigenschaften

  Magnesium silicate occurs as an odorless and tasteless, fine, whitecolored powder that is free from grittiness.

• Chemische Eigenschaften

  white to off-white fine powder

• Chemische Eigenschaften

  A synthetic, usually amorphous form of magnesium silicate in which the molar ratio of silicon dioxide to magnesium oxide is approximately 2.2 to 3.3. It occurs as a very fine, white, odorless, tasteless powder, free from grittiness. It is insoluble in water and in alcohol, but is readily decomposed by mineral acids. The pH of a 1 in 10 slurry is between 7.0 and 10.8.

• Verwenden

  A chromotographic adsorbant.

• Verwenden

  Magnesium Silicate is a white powder that is insoluble in water and functions as an anticaking agent. it is used in salt. it is also a process- ing aid and adsorbent which functions as an anticaking agent and remover of undesirable proteins during filtration. it is insoluble and a 10% slurry has a ph of approximately 7.0. it aids in the processing of beverages, food products, and pharmaceuticals by removing pro- tein/tannin complex constituents through surface area and adsorp- tive effects.

• Verwenden

  Florisil was used as column packing material in column chromatography. Florisil was used as an adsorbent in gas chromatography with electron capture detector (GC/ECD) , capillary column chromatography. and adsorption column chromatography. Florisil was used in clean-up procedures in gas chromatography-tandem mass spectrometry 4 and GC-FID.

• Vorbereitung Methode

  Magnesium silicate may be prepared from sodium silicate and magnesium sulfate. The silicate also occurs in nature as the minerals meerschaum, parasepiolite, and sepiolite.

• Allgemeine Beschreibung

  Florisil, adsorbent for the separation of lipids, is a commercially-prepared magnesia silica gel. It has a coarse mesh size which helps in rapid flow rate. Florisil is effective in promoting [1,3]-sigmatropic shift of myceophenolic acid related allyl phenyl ethers. Florisil cartridges are used in atmospheric sampling to assess possible interference from air contaminants.

• Hazard

  Toxic by inhalation, use in foods restricted to 2%.

• Pharmazeutische Anwendungen

  Magnesium silicate is used in oral pharmaceutical formulations and food products as a glidant and an anticaking agent.

• Sicherheit(Safety)

  Magnesium silicate is used in oral pharmaceutical formulations and is generally regarded as an essentially nontoxic and nonirritant material.
  Orally administered magnesium silicate is neutralized in the stomach to form magnesium chloride and silicon dioxide; some magnesium is absorbed. Caution should be used when greater than 50 mEq of magnesium is given daily to persons with impaired renal function, owing to the risk of hypermagnesemia.
  Reported adverse effects include the formation of bladder and renal calculi following the regular use, for many years, of magnesium silicate as an antacid.
