Abstract
금속알루미늄 조각과 alcohols을 반응시켜 Al-alkoxides를 합성하였으며 이것을 가수분해하여 얻은 Al-hydroxides와 시약 AlCl3로부터 얻은 Al-hydroxides를 여러 온도에서 소성하여 여러 상의 고순도 Al2O3를 제조하였다. 제조한 γ와 η상 알루미나의 촉매적 특성을 알아보았고, Al(OH)3로부터 α-Al2O3의 생성과정을 속도론적으로 고찰하였다.

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.
