Propylethylene (also known as 1-pentene) is an important linear alpha-olefin used as a chemical intermediate and industrial raw material. It is mainly used in the production of copolymers, polyethylene modifiers, plasticizers, synthetic lubricants, surfactants, and specialty chemicals. It is also used as a solvent and feedstock in organic synthesis and petrochemical applications.
