Ethylene is a hydrocarbon which is widely used in the chemical industry and as a natural plant hormone. It is used in many industrial reactions such as in polymerization, halogenations and hydrogenation, alkylation, hydration, oligomerization, and hydroformylation. A large amount of ethylene which is produced goes into the manufacturing of ethylene oxide, ethylbenzene, ethylene dichloride, and polyethylene. The applications of ethylene include those in packaging, trash liners, carrier bags, surfactants, detergents, automotive antifreeze, rubber, anesthetic agent, fruit ripening, and plastics.
