Alumina A, Activity: I, MP EcoChrom™, MP Biomedicals™

Description

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

• Alumina A is widely used to remove water from gas streams.
• Also used for its hardness and strength.
• It is widely used 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, and glucosides.
• Acidic alumina, is the weakest and least often used type.
• Alumina is useful for separation of acid pigments and strong acids.
• It can cause polymerization, condensation and dehydration reactions.
• Neither acetone nor ethyl acetate should be used as eluants, the latter being subject to saponification.
• It is used as a dosimeter for radiation protection and therapy applications for its optically stimulated luminescence properties.
