A process for separating linear alpha olefins from their mixture in a feed stream with olefins which are branched at the 2- and/or 3-position, the process comprising: a) contacting the feed stream with one or more linear polyaromatic compounds having 3 or more fused aromatic, optionally substituted, rings under conditions effective to form a linear polyaromatic compound-linear alpha olefin adduct; b) separating the linear polyaromatic compound-linear alpha olefin adduct from the reaction mixture; and c) dissociating the linear polyaromatic compound-linear alpha olefin adduct to form the linear polyaromatic compound and a linear alpha olefin composition, and optionally d) separating the linear polyaromatic compound formed in step c) from said linear alpha olefin composition.
Procédé permettant de séparer des .alpha.-oléfines linéaires de leur mélange, dans un flux d'alimentation, avec des oléfines ramifiées en position 2 et/ou 3, selon lequel: a) on met en contact le flux d'alimentation avec un ou plusieurs composés polyaromatiques linéaires renfermant trois, ou davantage, noyaux aromatiques condensés éventuellement substitués, dans des conditions efficaces pour former un composé d'addition constitué d'un composé polyaromatique linéaire et d'.alpha.-oléfines linéaires; b) on sépare ledit composé d'addition du mélange de réaction; et c) on dissocie ledit composé d'addition de façon à former le composé polyaromatique linéaire et une composition d'.alpha.-oléfines linéaires; et éventuellement d) on sépare le composé polyaromatique linéaire formé à l'étape c) de ladite composition d'.alpha.-oléfines linéaires.
