Abstract
|
|
|
|
Aluminum alkoxide, Al(OC3H7i)3 and Al(OC4H9s)3, were synthesized using aluminum sheet and corresponding alcohols to prepare various phase alumina in high purity. Aluminum hydroxides were prepared by hydrolysis of synthesized Al-alkoxides and from reagent AlCl3. The catalytic properties of γ and η-Al2O3 prepared at various temperatures were investigated and the reaction kinetics of α-Al2O3 formation from Al(OH)3 was considered.
