Title
(EN) PROCESS FOR THE PREPARATION OF ALPHA OLEFINS
(FR) PROCEDE POUR LA PREPARATION DES ALPHA-OLEFINES
Abstract
(EN) This invention relates to a process for the preparation of an alpha olefin product which comprises metathesizing an internal olefin under non-equilibrium conditions and thereby producing a lower boiling internal olefin product which is removed as formed, and a higher boiling mid-chain internal olefin product, thereafter contacting and reacting the higher boiling mid-chain internal olefin product with ethylene to produce an alpha olefin product having a narrow molecular weight range.
(FR) L'invention concerne un procédé pour préparer un produit alpha-oléfinique. Ce procédé consiste à assurer la métathèse d'une oléfine interne dans des conditions de non équilibre et à produire ainsi un produit oléfinique interne à faible point d'ébullition qui est retiré lors de sa formation, et un produit oléfinique interne de milieu de chaîne à point d'ébullition élevé. Après quoi, on place en contact et on assure la réaction du produit oléfinique de milieu de chaîne à point d'ébullition élevé avec de l'éthylène pour produire une alpha-oléfine présentant une plage de poids moléculaire étroite.
