  • Applications

    7-Hexadecene (CAS 18899-19-9) is a long-chain internal olefin that serves mainly as a chemical intermediate and feedstock for specialty polymers and surface-active materials. It can act as a monomer or comonomer in the synthesis of specialty polyolefins and copolymers, and can be functionalized (e.g., epoxidation or hydrofunctionalization) to furnish intermediates for coatings and adhesives. It can be hydrogenated to give saturated hydrocarbons for lubricants, waxes, or formulation aids. It may serve as a starting material for the synthesis of fragrance- and cosmetic-related derivatives, and can function as a reactive diluent or processing solvent in coatings and inks formulations. Its use is subject to local regulations and formulation limits.
