Process for preparing aluminum oxide masses with very narrow pore radius distribution

摘要

A process for the production of an aluminum oxide composition which includes subjecting an aluminoxane with a basic structural element of -Al-O-Al- or a basic oligomeric structural element of -Al-O-Al-O-Al-O-Al- to mild hydrolysis with at least one inert gas moistened below its dew point to produce a composition and subjecting the composition to thermolysis at temperatures from about 300 to about 900° C.
