Olefins

Alpha-olefin
... Alpha-olefins (or α-olefins) are a family of organic compounds which are olefins or alkenes with a chemical formula CxH2x, distinguished by having a double bond at ... There are two types of alpha-olefins, branched and linear (or normal) ... The chemical properties of branched alpha-olefins with a branch at either the second (vinylidene) or the third carbon number are significantly different from the ...

Naphthenic Oil - Different Types - Paraffinic
... as a feedstock in the petrochemical production of olefins ... The primary products of the cracking process are olefins (ethylene / ethene, propylene / propene and butadiene) ... The olefins are used as feedstocks for derivative units that produce plastics (polyethylene and polypropylene for example), synthetic fiber precursors (acrylonitrile ...

Shell Higher Olefin Process - Process
... The fraction containing C6 to C18 olefins has commercial value and is removed ... The remaining higher and lower olefins next undergo liquid-phase isomerization reactions using alkaline alumina catalyst leading to internal double bonds ... The internal olefins are reacted with an excess of ethylene with rhenium(VII) oxide supported on alumina as catalyst in an ethenolysis reaction, which causes the internal double bond to break up to ...

Linear Alpha Olefin
... Linear Alpha Olefins (LAO) or Normal Alpha Olefins (NAO) are olefins or alkenes with a chemical formula CxH2x, distinguished from other mono-olefins with a similar molecular formula by linearity of the ... Linear alpha olefins are a range of industrially important alpha-olefins, including 1-butene, 1-hexene, 1-octene, 1-decene, 1-dodecene, 1-tetradecene ...
