Abstract

Abstract Translated from French L'invention décrit un procédé de synthèse du butène-1 par dimérisation de l'éthylène en présence d'un catalyseur constitué par l'interaction, en milieu hydrocarboné, d'une part d'un trialkylaluminium, avec d'autre part un mélange en proportions voisines de la stoechiométrie entre un titanate d'alkyle et un éther. L'activité et la sélectivité sont meilleures que lorsqu'on ajoute l'éther à un mélange déjà formé de titanate d'alkyle et de trialkylaluminium. The invention describes a process for the synthesis of butene-1 by dimerization of ethylene in the presence of a catalyst constituted by the interaction, in a hydrocarbon medium, on the one hand of a trialkylaluminum, on the other hand in proportions close to the stoichiometry between an alkyl titanate and an ether. The activity and the selectivity are better than when the ether is added to a mixture already formed of alkyl titanate and trialkylaluminium.
