Alumina N, 32 to 63 μm, Active, MP EcoChrom™, MP Biomedicals™

Description

Used as an adsorbent, desiccating agent, and catalyst. EcoChrom™ Alumina N is an amphoteric oxide that is used in a variety of reactions that are useful industrially. It is commonly referred to as alumin.

Alumina N is an oxide of aluminum, occurring in nature as various minerals such as bauxite, corundum, etc. It catalyzes a variety of reactions that are useful industrially.

• In chemistry laboratories, as a medium for chromatography (available in basic, acidic and neutral formulations), as well as for alcohols, hydrocarbons, steroids, alkaloids and natural pigments.
• As an abrasive, due to its hardness and strength (e.g. as an inexpensive substitute for industrial diamond; used in many types of sandpaper in crystal form).
• Widely used to remove water from gas streams.
• In the manufacture of dental cements and refractories.
• Neutral alumina, (less active than the basic form) is useful for separation of aldehydes, ketones, quinones, esters, lactones, and glucosides.
• Acidic alumina (pH 4.5 when in water), 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.
