1-Octadecene is widely used in the production of polyethylene and polyalphaolefins (PAOs), which are essential in lubricants for automotive and industrial applications. It serves as a monomer in polymerization processes to create high-performance plastics and synthetic oils. Additionally, it is utilized in the synthesis of surfactants and emulsifiers, which are critical in detergents, personal care products, and industrial cleaning agents. In the field of organic synthesis, 1-octadecene acts as a solvent or intermediate for producing specialty chemicals, including pharmaceuticals and agrochemicals. Its role in the creation of nanomaterials, such as quantum dots and nanoparticles, is also notable, particularly in electronics and biomedical research.
