Description

Octadecene is a high-purity, long-chain α-olefin monomer essential for advanced polymer synthesis and specialty chemical manufacturing. Its linear C18 structure provides a critical balance of reactivity and hydrocarbon character, enabling precise material engineering. This product is vital for R&D and production teams in the polymer, surfactant, and lubricant industries seeking to develop high-performance materials with tailored properties.

Application

• Polymer & Copolymer Production: Serves as a key comonomer for producing linear low-density polyethylene (LLDPE), polyalphaolefins (PAOs), and other high-value polymers.
• Surfactant & Detergent Intermediates: Used in the synthesis of olefin sulfonates and other specialty surfactants for industrial and consumer cleaning formulations.
• Lubricant & Oil Additive Synthesis: A fundamental building block for manufacturing synthetic lubricant base stocks (PAOs) and performance-enhancing additives.
• Organic Synthesis & Fine Chemicals: Acts as a versatile intermediate in organic reactions, including hydroformylation and alkylation, to produce plasticizers, flavors, and fragrances.
• Research & Development: Employed in academic and industrial labs for catalysis studies, material science research, and developing novel chemical processes.

Quality Control

Our Octadecene is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed against rigorous internal specifications, which typically include identity confirmation, assay, and impurity profile checks. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

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 strong oxidizing agents. For long-term stability, it is recommended to store under an inert atmosphere (e.g., nitrogen) to minimize oxidation. Recommended storage temperature is 15-25°C.
