CAS 112926-00-8 Dehydration And Drying Agent Silica Gel Moisture And Humidity Control

 

Description:

Silica gel is a porous, granular form of silicon dioxide (SiO2). It is synthetically produced by the reaction of sodium silicate with sulfuric acid, resulting in the formation of a colloidal suspension that is then dried and processed into granules. Silica gel has a high surface area and a network of interconnected pores, giving it excellent adsorption properties.

 

Technical Data:

Chemical Formula: SiO2
Molecular Weight: 60.08 g/mol
Appearance: Amorphous, granular or bead form
Pore Size: Varies (micro- to mesoporous)
Surface Area: Typically ranges from 300 to 800 m2/g

 

Application:

1. Moisture and Humidity Control: Silica gel is widely used as a desiccant for controlling moisture and humidity levels in various applications. It has a strong affinity for water molecules and can effectively absorb moisture from the surrounding environment. Silica gel packets are commonly found in packaging for electronics, leather goods, pharmaceuticals, and food products to prevent moisture damage.

2. Dehydration and Drying Agent: Silica gel is used for dehydration and drying purposes in various industries. It can be utilized to remove moisture from gases and liquids, including compressed air systems, natural gas pipelines, and drying solvents in laboratory settings. Silica gel is also employed for drying flowers, preserving seeds, and protecting sensitive items like cameras, lenses, and musical instruments.

3. Catalyst Support: Silica gel serves as a support material for catalysts in chemical reactions. Its high surface area and pore structure make it an ideal substrate for anchoring catalysts, allowing for increased surface contact and reaction efficiency. Silica gel-based catalysts find applications in the petrochemical industry, oil refining, and various organic synthesis processes.

4. Chromatography: Silica gel is commonly used as a stationary phase in column chromatography. Its porous structure enables the separation and purification of different compounds based on their affinity and interaction with the silica gel surface. Silica gel columns are employed in analytical chemistry, pharmaceutical research, and purification of natural products.

5. Gas and Liquid Chromatography: Silica gel is utilized as a stationary phase in gas and liquid chromatography, allowing for the separation and analysis of complex mixtures. In gas chromatography, it is packed into columns to separate volatile compounds based on their interaction with the silica gel surface. In liquid chromatography, it is used in stationary phases for high-performance liquid chromatography (HPLC).

6. Silica Gel Packs for Storage: Silica gel packets are commonly used in storage containers for preserving the quality and longevity of various items. They help prevent moisture damage, mold, and mildew growth by adsorbing excess moisture in enclosed spaces. Silica gel packs are often found in shoeboxes, closets, camera bags, and archival storage for documents and photographs.
