Olefins

Olefins or alkenes are unsaturated aliphatic hydrocarbons containing C=C double bonds. They are reactive and relatively unstable compounds due to the double bond and are subject to oxidation making them undesirable in petroleum solvents and lubricating oils. The olefins ethylene, propylene and butene are used as monomers in the manufacturing of plastic polymers such as polypropylene and polyethylene.
