Alumina, Activity: II-III, MP EcoChrome™

MP EcoChrom™ Alumina, Activity II-III is an economical adsorbents of medium activity.

Is often used where:

• Activated charcol can not be used due to its organic nature
• The cation exchange properties of basic alumina are desired

MP EcoChrom™ Alumina, Activity II-III is:

• Suitable for the development of separation methods and for technical separations where a custom-made adsorbents for special separation is not available
• An oxide of aluminum, occurring in nature as various minerals such as: bauxite, corundum, etc.
• Used as:
  • An adsorbent
  • A desiccating agent and a catalyst, in the manufacture of dental cements and refractories.

Application Notes:

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

It is 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 and 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
• TLC
