Alumina N, 32 to 63 μm, Non-active, MP EcoChrome™

MP EcoChrom™ Alumina N is an oxide of aluminum, occurring in nature as various minerals such as bauxite, corundum, etc.

It is used as:

• An adsorbent
• A desiccating agent
• A catalyst
• In the manufacture of dental cements and refractories

Application Notes:

MP EcoChrom™ Alumina N catalyses a variety of reactions that are useful industrially.

It is widely used:

• To remove water from gas streams
• For its hardness and strength
• As an abrasive, including as a much less expensive substitute for industrial diamond
  • Many types of sandpaper use aluminium oxide crystals
• In chemistry laboratories, alumina is a medium for chromatography, available in basic (pH 9.5), acidic (pH 4.5 when in water) and neutral formulations, as well as for:
  • Alcohols
  • Hydrocarbons
  • Steroids
  • Alkaloids
  • Natural pigments
  • Neutral alumina (less active than the basic form) is useful for separation of:
    • Aldehydes
    • Ketones
    • Quinones
    • Esters
    • Lactones
    • Glucosides
  • Acidic alumina, is the weakest and least often used type and is useful for separation of acid pigments and strong acids. It can cause:
    • Polymerization
    • Condensation
    • Dehydration reactions
  • Neither acetone nor ethyl acetate should be used as eluants, the latter being subject to saponification.
• A dosimeter for radiation protection and therapy applications for its optically stimulated luminescence properties

Usage Statement: Unless specified otherwise, MP Biomedical's products are for research or further manufacturing use only, not for direct human use.

Key Applications:

• Chromatography
• Adsorbants
