1hexene

1-hexene, or hex-1-ene, is an unsaturated hydrocarbon in the alkene family with the formula C6H12. It has a terminal carbon–carbon double bond (CH2=CH–), classifying it as an alpha-olefin. At room temperature it is typically a colorless liquid with a distinct hydrocarbon odor.

As an olefin, 1-hexene undergoes a variety of addition reactions that add across the C=C bond. It participates in hydrohalogenation, hydroboration-oxidation, hydration to give alcohols, and epoxidation. It also readily undergoes polymerization, either by radical, cationic, or coordination-catalyzed mechanisms, to form poly(hex-1-ene) or copolymers with other olefins.

Industrial production and uses are centered on its role as a versatile monomer and comonomer. 1-Hexene is produced and purified for use in the synthesis of polyolefins, especially as a co-monomer in the production of linear low-density polyethylene (LLDPE) and other polyethylene grades to improve flexibility and processing properties. It also serves as a chemical intermediate in the manufacture of surfactants, lubricants, and specialty chemicals.

Safety and handling: 1-hexene is a flammable liquid. Vapors can form explosive mixtures with air, and ignition sources should be avoided. It should be stored in a cool, well-ventilated area away from oxidizers, and handled with appropriate personal protective equipment to minimize exposure.
