Application
Aluminum oxide (Alumina) may be used for the removal of peroxides from the dehydration solvent (tetrahydrofuran THF) in a protocol. Protocol involved the high resolution study of fine brain anatomy of fluorescently labeled mouse brains.[1]It may be used in the fabrication of polycrystalline lithium iodide-Aluminum oxide solid electrolytes. The incorporation of aluminum oxide remarkably increased the conductivity of lithium iodide. Aluminum oxide (acidic) can be used as an adsorbent for column chromatography.[5] It may be used as an active surface for the acylation of aromatic ethers with carboxylic acids in the presence of trifluoroacetic anhydride under solvent-free conditions.

Purpose
For R&D use onlynot for drug household or other uses.

General Description
Brockmann aluminum oxides are suitable for column chromatography and adsorptive filtration. The mechanism of formation of protective scales of -Al2O3 (aluminum oxide) on surfaces of binary M-Al (M Fe Ni or Co) alloys at high temperatures has been studied. Activated aluminum oxides having different acidities and water concentrations (having Brockmann activity I-V) can easily detect various types of water (namely free water pore water and bound water) on the aluminum oxide present in soils.
