1-Octene is an organic compound with a formula CH2CHC6H13. 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. It is a colourless liquid.
In industry, 1-octene is commonly manufactured by two main routes: oligomerization of ethylene and by Fischer-Tropsch synthesis followed by purification. Another route to 1-octene that has been used commercially on a small scale is dehydration of alcohols. Prior to the 1970s, 1-octene was also manufactured by thermal cracking of waxes, whereas linear internal octenes were also manufactured by chlorination/dehydrochlorination of linear paraffins.
There are five commercial processes that oligomerize ethylene to 1-octene. Four of these processes produce 1-octene as a part of a wide distribution of alpha-olefins. In typical circumstances, 1-hexene content of the entire distribution of alpha-olefins ranges from about 25% of the distribution in the Ethyl (Innovene) process to about 8% of distribution in some modes of the Gulf (CP Chemicals) and Idemitsu processes.
