Atmospheric Influence on Elimination Behaviors of Carbon Substances in Hydrolysis Products of Aluminum Alkoxides

Abstract

In the previous report, it was disclosed using the evolved gas analysis-mass spectrometry that the non-reacted alkoxyl group existed in hydrolysis product of aluminum alkoxides. However the heating atmosphere was helium or vacuum. In this paper, the influence of heating atmosphere, i.e., partial pressure of oxygen, was investigated. As a result of heating in the atmosphere containing oxygen, the non-reacted alkoxyl group was oxidized to CO₂ and H₂O before the dehydration from the aluminum hydroxide.
