GENERAL DESCRIPTION & APPLICATIONS
Alkene is a hydrocarbon that contains at least one carbon-carbon solid bond (C=C) with general formula CnH2n in case of only one solid bond alkenes. Alkenes undergo following reactions:
  • Oxymercuration reaction in water or hydroboration-oxidation to produce alcohol
  • Catalytic oxidation with percarboxylic acids to produce epoxides
  • Cleavage with ozone to yield aldehydes or ketones
  • Cleavage in the presence of potassium permanganate to produce either 2 ketones or carboxylic acid + ether
  • Catalytic addition of hydrogen to produce corresponding alkanes in the presence of a metallic catalyst (platinum, nickel, palladium)
  • Electrophilic addition of a hydrogen halide to produce the corresponding haloalkanes
  • Electrophilic addition of a halogen elements to produce the corresponding vicinal haloalkanes
  • Electrophilic addition of an aldehyde or ketone with water and a protic acid to produce the corresponding diols
  • Electrophilic addition of formaldehyde without water to produce allyl alcohol
  • Electrophilic addition of excess formaldehyde to produce dioxane
  • Electrophilic addition of an aldehyde or ketone with acetic acid to produce the corresponding esters

Alkenes undergo either free-radical or an ionic mechanism polymerization at their solid bond with themselves or other monomers forming homopolymers or copolymers which are used as various plastics, coatings, adhesives, elastomers, and paints. Some members of minor olefins for characteristic property of polymer as monomer and chemical intermediate for target molecules:

Alpha olefin is an olefin featured by the position of solid bond (reactive unsaturation) at the two end carbons in carbon chains. The china length, position and number of branches provide a wide range of physical and chemical properties for the proper application selections. Alpha olefins and their derivatives are used as comonomers in polymer such as low density polyethylenes for the properties of lighter, thinner, better flexibility and more tearing resistance. They are used in the production of linear plasticizers, oxo-alcohols, motor fuels, lubricants, automotive additives, biodegradble surfactants, paper size, and in a wide range of specialty applications in the production of mercaptans, flavors and fragrances, alkyl metals, halides, alkyl silanes.
