Abstract

A process for the preparation of a transition alumina, with the global formula Al4O9H6, which has neutralizing, regulatory and antiseptic properties, characterized by hydrolyzing aluminum isopropylate by means of a mixture of water and isopropanol, at the reflux temperature of the mixture, the ratio of water to isopropylate of 2.25 moles of water per mole of isopropylate, reflux being maintained for about half an hour and then separating the product obtained by draining, after concentrating the reaction mixture by distillation of most of the isopropanol in excess.
