Preparation method of meso-porous alumina and catalytic synthesis of alpha-tetralone

Abstract

The invention provides a method for preparing cobalt-doped mesoporous alumina by taking a rubber latex as a biological template, and a method for catalytically oxidizing tetralin into tetralone under liquid phase. The invention relates to the method for preparing the cobalt-doped mesoporous alumina by taking the rubber latex as the template, and the method for synthesizing tetralone. The invention aims to develop a method which is used for preparing the cobalt-doped mesoporous alumina by taking the rubber latex as the biological template and a high-conversion and high-selectivity method which is used for catalytically oxidizing tetralin into tetralone under the liquid phase, and comprises the following steps: a mesoporous material is taken as a heterogeneous catalyst, and tetralin is catalytically oxidized into tetralone under the low temperature liquid phase. The experimental results show that the conversion rate of the tetralin reaches 80.3 percent and the selectivity of tetralone reaches 74.5 percent.

[0002] Various forms of alumina play an important role in the development of catalysis. Nano-mesoporous alumina (Al 2 o 3 ) Molecular sieves with non-porous Al 2 o 3 The different excellent properties of nanomaterials, it not only has the unique surface effect, volume effect, quantum size effect and macroscopic quantum tunneling effect of nanomaterials, but also has a higher specific surface area, larger pore size (compared to microporous materials) and The long-range ordered pore arrangement has broad application prospects in the field of catalysis. In recent years, the synthesis of mesoporous materials mainly adopts methods such as hydrothermal synthesis, room temperature ...
