Description

Molecular Sieves CAS NO 1327-44-2 are highly porous, crystalline aluminosilicates engineered for selective adsorption based on molecular size and polarity. Their core value lies in providing exceptionally efficient and reliable drying, purification, and separation for critical industrial processes. This product is essential for industries requiring stringent control over moisture and gas composition, including petrochemical refining, natural gas processing, and the production of insulated glass windows.

Application

• Gas Drying & Purification: Deep dehydration of natural gas, cracked gas, synthesis gas (syngas), and air prior to cryogenic separation.
• Liquid Drying: Removal of trace water from organic solvents, liquid hydrocarbons, and refrigerants to prevent corrosion and side reactions.
• Insulated Glass Desiccant: Adsorption of residual moisture and processing by-products within the airspace of double- or triple-pane insulating glass units to prevent fogging.
• Hydrocarbon Separation: Selective adsorption for separating normal paraffins from iso-paraffins and other branched-chain molecules in refining and petrochemical operations.
• Air Conditioning Systems: Drying of refrigerant circuits to prevent ice formation and acid generation, protecting compressors and system integrity.
• Catalyst Support & Carrier: Utilized as a stable, high-surface-area support material for various catalysts in chemical synthesis.
• Laboratory & Instrumentation: Protection of sensitive equipment and creation of dry atmospheres in gloveboxes, FTIR spectrometers, and other analytical instruments.

Quality Control

Our Molecular Sieves are manufactured under a strict quality management system. Each batch is tested for critical performance parameters including adsorption capacity, crush strength, bead size distribution, and bulk density to ensure consistency and reliability. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed, moisture-proof container. Due to its hygroscopic nature, the product must be stored in a cool, dry, and well-ventilated area. Minimize exposure to ambient air during handling to prevent premature moisture uptake and maintain optimal adsorption performance.
