| 摘要 |
The present invention relates to a method for preparing boehmite and gamma-alumina with high surface area, and more particularly, to a method comprising hydrolysis of aluminum alkoxides to produce boehmite and calcination to produce gamma-alumina, wherein an alcohol is used as a reaction solvent and a small amount of water and a particular organic carboxylic acid are added so that not only the reaction solvent is easily recovered and energy required for drying is significantly reduced but also it provides boehmite having nano-sized particles, high surface area, and high purity. Further, the prepared gamma-alumina may be suitable for high value added industrial applications such as manufacture of adsorbents, catalysts, catalyst supports and chromatography materials.
