Description

Alkenes, C24-28 α- is a defined mixture of long-chain linear α-olefins, primarily in the C24 to C28 carbon range. This high-purity hydrocarbon blend is valued for its role as a crucial intermediate in the synthesis of specialized surfactants, lubricant additives, and polymeric materials. It is essential for manufacturers in the chemical, petrochemical, and specialty materials sectors seeking consistent raw materials for performance-driven applications. The product is supplied with full traceability and quality documentation.

Application

• Surfactant & Detergent Intermediate: Acts as a key feedstock for the production of high-molecular-weight alcohol ethoxylates and sulfonates used in industrial and institutional cleaning formulations.
• Lubricant & Fuel Additive Synthesis: Serves as a precursor for polyalphaolefins (PAOs) and other olefin oligomers that enhance viscosity index, thermal stability, and pour point in synthetic lubricants.
• Polymer Comonomer: Used as a comonomer in the production of linear low-density polyethylene (LLDPE) and other polyolefins to modify density and mechanical properties.
• Oilfield Chemicals: Employed in the synthesis of drilling fluid additives and demulsifiers for crude oil processing.
• Paper Sizing Agents: A raw material for creating alkyl ketene dimer (AKD) and alkenyl succinic anhydride (ASA) sizing agents that impart water resistance to paper and paperboard.
• Specialty Chemical Synthesis: Provides a long-chain alkyl building block for pharmaceuticals, agrochemicals, and cosmetic ingredients.

Quality Control

Our Alkenes, C24-28 α- is manufactured under a stringent quality management system. Each batch undergoes comprehensive analysis including gas chromatography (GC) to verify carbon number distribution, α-olefin content, and purity. We provide full traceability and a Certificate of Analysis (COA) with every shipment, detailing key parameters such as assay, moisture content, and specific gravity to ensure compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to minimize exposure to air and moisture.
