The only commercial process to isolate 1-octene from a wide mixture of C 8 hydrocarbons is practiced by Sasol, a South African oil and gas and petrochemical company.
12.
The one on the left is a bicyclo [ 2.2 . 2 ] octene, which, at 200 �C, extrudes ethylene in a retro-Diels Alder reaction.
13.
An example of Karasch addition is the synthesis of " 1, 1, 3-trichloro-n-nonane " from 1-octene, chloroform and ferric chloride.
14.
Even polyethylenes copolymerized with a small amount of alpha-olefins ( such as 1-hexene, 1-octene, or longer ) are more flexible than simple straight-chain high-density polyethylene, which has no branching.
15.
For instance, copolymers with short chain branching such as linear low-density polyethylene ( a copolymer of ethylene and a higher alkene such as hexene or octene ) require the use of Analytical Temperature Rising Elution Fractionation ( ATREF ) techniques.
16.
In 1975 Katz also arrived at a metallacyclobutane intermediate consistent with the one proposed by Chauvin He reacted a mixture of cyclooctene, 2-butene and 4-octene with a molybdenum catalyst and observed that the unsymmetrical C14 hydrocarbon reaction product is present right from the start at low conversion.
17.
The alkene is classified as a higher olefin and alpha-olefin, meaning that the double bond is located at the alpha ( primary ) position, endowing this compound with higher reactivity and thus useful chemical properties . 1-Octene is one of the important linear alpha olefins in industry.
18.
In recent years, two on-purpose 1-octene technologies have been commercialised : a butadiene telomerisation plant ( Dow, Tarragona ), and a 1-heptene to 1-octene plant based on a Fischer-Tropsch-derived C 7 olefin stream ( Sasol, Secunda ).

20.
For commercial purposes, Sasol employs Fischer-Tropsch synthesis to make fuels from synthesis gas derived from coal and recovers 1-octene from these fuel streams, where the initial 1-octene concentration in a narrow distillation cut may be 60 %, with the remainder being vinylidenes, linear and branched internal olefins, linear and branched paraffins, alcohols, aldehydes, carboxylic acids, and aromatic compounds.
