Abstract
This invention relates to aluminium compounds and their preparation. In accordance with the invention a peptizable alumina hydrate is prepared by hydrolyzing an aluminium alkoxide at a water:aluminium ratio at or near the stoichiometric value. One example of an aluminium alkoxide which has been hydrolyzed in accordance with the present invention is aluminium sec-butoxide (Al(OC.sub.4 H.sub.9).sub.3.sup.s); thus alkoxide has been hydrolyzed at water:aluminium ratios of 3:1 and 4:1 to give peptizable alumina hydrates. Cold water (e.g. at 16.degree.-22.degree. C.) and aluminium alkoxide are preferably brought together to effect the hydrolysis.
