Description

4-Decene is a high-purity, straight-chain alpha olefin with the CAS registry number 19689-18-0, serving as a versatile intermediate in organic synthesis and polymer chemistry. Its linear C10 structure and terminal double bond make it a valuable building block for creating specialty chemicals, surfactants, and performance materials. This product is essential for R&D laboratories and industrial manufacturers in the petrochemical, lubricant, and specialty polymer sectors seeking reliable, high-quality raw materials.

Application

• Chemical Intermediate: A key monomer for the synthesis of higher alcohols, acids, amines, and other derivatives via reactions like hydroformylation, epoxidation, and hydration.
• Polymer & Co-polymer Production: Used as a comonomer in the production of linear low-density polyethylene (LLDPE) and other polyolefins to modify properties such as density and flexibility.
• Surfactant & Detergent Manufacturing: Acts as a feedstock for producing biodegradable, linear alkylbenzene sulfonates (LAS) and alcohol ethoxylates used in industrial and household cleaners.
• Lubricant & Fuel Additive Synthesis: Employed in creating synthetic lubricant base oils and performance-enhancing additives for automotive and industrial applications.
• Organic Synthesis & Fine Chemicals: Utilized in research and development for constructing complex organic molecules, including pharmaceuticals and agrochemicals.
• Plasticizer Alcohols: A precursor in the manufacture of C10 plasticizer alcohols, which are esterified to produce phthalate and non-phthalate plasticizers for PVC and other polymers.

Quality Control

Our 4-Decene is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including Gas Chromatography (GC) to verify identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment, ensuring full traceability and compliance with customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat, sparks, and open flames. Recommended storage temperature is between 2°C and 25°C. Keep container tightly sealed when not in use to prevent evaporation and minimize exposure to air.
