Title (EN) MAGNESIUM DICHLORIDE-ETHANOL ADDUCTS AND ATALYST COMPONENTS OBTAINED THEREFROM
(FR) ADDITIFS A BASE DE DICHLORURE DE MAGNESIUM ET D'ETHANOL ET COMPOSANTS CATALYSEURS OBTENUS A PARTIR DE CES ADDITIFS
Abstract: front page image
(EN)Adducts are provided comprising MgCl2, ethanol and a Lewis base (LB), said compounds being present in molar ratios defined by the following formula MgC12•(EtOH)n(LB)p in which n is from 2 to 6 and p has values satisfying the following equation p/(n+p)≤0.1. The said adducts can be used as precursor in the preparation of high activity ZN catalysts.
(FR)L'invention concerne des additifs comprenant MgCl2, de l'éthanol et une base de Lewis (LB), lesdits composants étant présents dans des proportions molaires définies par la formule MgC12 (EtOH)n(LB)p dans laquelle n est compris entre 2 et 6 et p a des valeurs qui satisfont à l'équation p/(n+p)=0,1. Ces additifs peuvent s'utiliser en tant que précurseurs dans la préparation de catalyseurs ZN à activité intense.
