摘要：

Thermal reaction of aluminum isopropoxide in glycols at 300°C yielded the glycol derivatives of boehmite. The physical properties of the products and the aluminas obtained by calcination strongly depended on the crystallite size of the boehmite derivatives, which seems to be controlled by the heterolytic cleavage of the C‐O bond of HO(CH2)nOAI = formed by alkoxide exchange between aluminum alkoxide and glycol. The product had a unique honeycomb texture, which was preserved on calcination to form a transition alumina. Copyright © 1990, Wiley Blackwell. All rights reserved
