Why does hydrogen peroxide need stabilization?
Hydrogen peroxide is a strong oxidizing agent, but it rapidly decomposes into water and oxygen under the catalysis of light, heat, or trace metal ions (such as iron and copper). This spontaneous decomposition not only reduces the effective concentration of hydrogen peroxide, affecting its performance, but can also generate high pressure in sealed containers, posing a risk. Therefore, finding a highly efficient and safe stabilizer is crucial, and activated alumina is an ideal material for solving this problem.
Characteristics of Activated Alumina in Hydrogen Peroxide Applications:
Activated alumina is a porous, highly dispersed solid material produced by the heating and dehydration of aluminum hydroxide. Its unique physical and chemical properties make it excellent for hydrogen peroxide applications.
1. Large Specific Surface Area and Highly Developed Pore Structure
Its Role in Hydrogen Peroxide: It strongly adsorbs trace amounts of heavy metal ions and impurity particles in hydrogen peroxide. Through physical adsorption and chemical bonding, activated alumina locks them in, thereby breaking the catalytic chain of the decomposition reaction at its source and greatly improving the storage stability of hydrogen peroxide.
2. Ideal Surface Chemical Properties
Its Role in Hydrogen Peroxide: The surface of activated alumina has amphoteric properties, possessing both Lewis acid and Lewis base sites. Hydrogen peroxide decomposes extremely rapidly in alkaline environments. High-quality activated alumina, through strict process control, can provide a relatively neutral or weakly acidic surface microenvironment.
3. High Mechanical Strength and Regular Shape
In hydrogen peroxide: High strength ensures it is not easily broken or pulverized during packed beds, reaction towers, or transportation, avoiding pipeline blockage and product contamination caused by pulverization. Its regular shape ensures low resistance and uniform distribution of fluid, facilitating continuous industrial operation.
4. Chemical Inertness and Safety
In hydrogen peroxide: This inertness ensures it does not consume hydrogen peroxide or introduce new impurities. It ensures the purity and safety of the hydrogen peroxide product, meeting the requirements for high-purity applications.
How to Choose High-Quality Activated Alumina for Hydrogen Peroxide?
Purity: High-purity, low-sodium alumina minimizes impurity introduction.
Specific Surface Area and Pore Volume: A larger specific surface area generally means a higher adsorption capacity.
Strength: High abrasion resistance ensures a long service life.
Particle Size Specification: Select a suitable and uniform particle size based on your equipment.
