General description Brockmann aluminum oxides are suitable for column chromatography and adsorptive filtration. The product is basic activated aluminum oxide (Alumina, Al 2 O 3) having an activity grade Brockman I.The mechanism of formation of protective scales of 2 O 3 on surfaces of binary M-Al (M Fe, Ni or Co) alloys at high temperatures has been
Alumina can act as a weak ion exchanger demonstrating anionic or cationic properties, while additionally acting as an adsorbent. Alumina, due to its unique biological characteristics, is a special adsorbent for use in separation sciences. These active media are available in three different grades as per their application.

Alumina, Standard Activity I is a good all-purpose adsorbent for laboratory as well as process use.Alumina, Standard Activity I is similar to the Alumina, Activity Super I in that both are standardized. See of Activity using the Brockmann and Schodder for measuring the precise activity of
alumina has not often been used for the fractionation of petroleum- and coal-derived liquids. Nevertheless, it possesses the potential for an excellent separation of nitrogen compounds As opposed to neutral alumina its basic properties are responsible for the strong retention of compounds with hydrogen-donating
acetate and basic alumina catalyzed efficiently the Knoevenagel condensation of aldehydes and ketones with active methylene compounds under solvent-free condition where olefinic products were obtained in high yields. Article Metrics Views 566.
