Activated aluminum oxide is one of the most important materials in the fine chemical industry, and is widely used in the preparation of high-value added chemicals, catalysts, adsorbents, fillers, etc. Below, my company will explain the properties of activated aluminum oxide, its preparation methods, and its application in the fine chemical industry.
一,the property of active aluminum oxide
Activated aluminum oxide, also called γ-aluminum oxide, is a kind of crystalline form of aluminum oxide, the crystal structure of which is the most dense stacking. Activated aluminum oxide has excellent surface area, large hole diameter, high hole capacity, excellent thermal stability and chemical inertness, etc. Because its surface contains a large amount of active aluminum oxide hydroxy groups, activated aluminum oxide has excellent adsorption, catalysis, dispersibility and water resistance, and is a material with high application value.
二,active aluminum oxide preparation method
The preparation method of activated aluminum oxide mainly includes heat method, water heat method, solvent-gel method, mechanical mixing method, ion exchange method, etc. Among them, the solvent-gel method is one of the most widely used methods at present. The method is mainly to mix aluminum chloride, such as aluminum chloride, and sodium hydroxide, etc.
三,The application of active aluminum oxide in the fine chemical industry
1. catalyst
Activated aluminum oxide is one of the important components of catalysts, widely used in the fields of petroleum industry, chemical industry, organic synthesis, etc. Activated aluminum oxide can be used as a carrier, carrying different types of catalyst metals, such as platinum, cobalt, etc., so that the activity and selectivity of the catalyst can be improved.
2. separate material
Activated aluminum oxide has excellent adsorption properties and dispersion, and has a wide range of applications in the preparation of separation materials. For example, activated aluminum oxide can be used as a stationary phase, combined with some liquid phase, preparation of color spectrum column, used in biological separation fields and environmental analysis fields.
3. stuffing
Activated aluminum oxide can also be used as a filler material, used to prepare various high-efficiency thermal insulation materials and high-pressure plastic, etc.
4. Adsorbent
Active aluminum oxide has a wide range of adsorption capacity, and can be used to adsorb heavy metal ions, dyes, organic acids and organic bases in waste water and other harmful substances, thereby effectively removing them, which has important environmental significance.
In summary, activated aluminum oxide has important application value in the fine chemical industry. In the future, with the continuous development of the fine chemical industry, I believe activated aluminum oxide will play an increasingly important role, becoming one of the indispensable materials in the fine chemical industry.
