摘要：
A process includes a step of melting aluminium alkoxide in hexylene glycol (2-methyl 2,4-pentonediol). Then, the solution is subject hydrolysis. During this, hydrolysis and dehydrating condensation of hexylene glycol is controlled by alkoxide. This is found effective for obtaining alumina having uniform porous structure with high specific surface area.
